Why AC servo motor need a drive

Some time ago, a few students asked me why the AC servo motor needs drive? At that time, I told them at that time.

We know that there are many parameters of the servo motor, such as speed, torque, position and so on.

In order to make it easier to understand, I am here to give an example. AC motor speed is generally 1000 to 3000 r / min, the general power supply is 220V, or 380V, 50Hz, such as Delta AC servo motor, , but sometimes we do not want the motor speed is always the same, so we can change the frequency of the motor to change the way Of the rotational speed. Then we need to be accompanied by such a device to control the motor speed.

AC servo motor and drive kit

Servo motor control is very complex, Such as :Leadshine AC servo motor need to change the frequency, voltage, current, in order to achieve the motor speed, torque, position of the overall control, servo drive is used for this purpose. Servo motor is only responsible for how much you give me the frequency, voltage, I will do the appropriate thing. Frequency, voltage changes, the direction of change, etc. are responsible for changes by the servo controller.

Comparing induction motors, permanent-magnet motors, and servomotors

Designers and motor personnel advantage from discovering a supplier that’s an skilled resource of info to assist in pragmatic motor choice. Involve application specialists as early as you possibly can, as they are able to assist create prototypes, custom electrical and mechanical styles, mountings, and gearboxes. This also reduces expenses related with shorter lead occasions and rush delivery.

Servo motors can offer higher performance, faster speeds, and smaller sizes. PM synchronous motors offer advantages on high-energy- consuming and high-dynamic applications, compared to induction motors. Variable frequency drives used with asynchronous motors also can be used with synchronous delta servo motor, producing higher efficiencies than an asynchronous motor, using perhaps 30% less energy in positioning applications.Here recommend you delat servo motor.

Induction motor systems (lower cost, rugged, reliable, and well known) can offer an alternative to mitsubishi servo motors systems (the traditional, established solution) for certain applications. This, of course, is based on similar electronic controls being used (with the latest technology and approximately the same cost), leaving the cost of motors the differentiating issue.

Overview of the pros and cons of each motor type

Induction motor

SPEEDLess speed range than PMAC motors • Speed range is a function of the drive being used — to 1,000:1 with an encoder, 120:1 under field-oriented control

EFFICIENCYEven NEMA-premium efficiency units exhibit degraded efficiencies at low load

RELIABILITYWaste heat is capable of degrading insulation essential to motor operation • Years of service common with proper operation

POWER DENSITYInduction produced by squirrel cage rotor inherently limits power density

ACCURACYFlux vector and field-oriented control allows for some of accuracy of servos

COST - Relatively modest initial cost; higher operating costs


SPEEDVFD-driven PMAC motors can be used in nearly all induction-motor and some servo applications • Typical servomotor application speed — to 10,000 rpm — is out of PMAC motor range.

EFFICIENCY - More efficient than induction motors, so run more coolly under the same load conditions

RELIABILITY – Lower operating temperatures reduces wear and tear, maintenance • Extends bearing and insulation life • Robust construction for years of trouble-free operation in harsh environments

POWER DENSITY – Rare-earth permanent magnets produce more flux (and resultant torque) for their physical size than induction types

ACCURACY – Without feedback, can be difficult to locate and position to the pinpoint accuracy of servomotors

COST – Exhibit higher efficiency, so their energy use is smaller and full return on their initial purchase cost is realized more quickly


SPEED – Reaches 10,000 rpm • Brushless DC servomotors also operate at all speeds while maintaining rated load

EFFICIENCY – Designed to operate over wide range of voltages (as this is how their speed is varied) but efficiency drops with voltage

RELIABILITY – Physical motor issues minimal; demanding servo applications require careful sizing, or can threaten failure

POWER DENSITY – Capable of high peak torque for rapid acceleration

ACCURACY – Closed-loop servomotor operation utilizes feedback for speed accuracy to ±0.001% of base speed

COST – Price can be tenfold that of other systems

In the end, all industrial motor subtypes have strengths and weaknesses,plus application niches for which they’re most suitable. For example, many industrial applications are essentially constant torque, such as conveyors. Others, such as centrifugal blowers, require torque to vary as the square of the speed. In contrast, machine tools and center winders are constant horsepower, with torque decreasing as speed increases. Which motors are most suitable in these situations? As we will explore, the speed-torque relationship and efficiency requirements often determine the most appropriate motor.

What is a Servo Control System

A servo control system is one of the most important and widely used forms of control system. Any machine or piece of equipment that has rotating parts will contain one or more servo motor drive control systems. The job of the control system may include:

* Maintaining the speed of a motor within certain limits, even when the load on the output of the motor might vary. This is called regulation.
* Varying the speed of a motor and load according to an externally set programme of values. This is called set point (or reference) tracking.

Servo motors are brushed or brushless DC motors with feedback, typically encoder or resolver. They can be rotary or linear motors. They require a complex closed loop control algorithm (such as the classic PID method). Normally the control loop has to be tuned, and Delta servo motor dither can be a problem.. Due to the added control and feedback, typically servo systems are more expensive than stepper systems.

Servo motors typically have a peak torque of 3-10x the continuous torque, their torque curve is much flatter than the stepper curve, and the maximum speeds are much higher. Peak torque is a great thing; often, a system just needs extra power for a short time to accelerate, overcome friction, or such.

Our daily lives depend upon servo controllers. Anywhere that there is an electric motor there will be a servo control system to control it. Servo control is very important. The economy of the world depends upon servo control (there are other things to be sure – but stay with me on the control theme). Manufacturing industry would cease without servo systems because factory production lines could not be controlled, transportation would halt because electric traction units would fail, computers would cease because disk drives would not work properly and communications networks would fail because network servers use hard disk drives. Young people would become even more unbearable and they would complain more than they do now, because their music and games systems will not work without servo control.

Servo control systems are that important and it is vital to know about them. So pay attention and sit up straight – you are not on holiday and I am not writing this for the good of my health.

Basic Configurations of Gear Reducers

NMRV030Gear redcuers are categorized according to the orientation of the input and output shafts, right-angle or parallel-shaft reducers. These different arrangements use different typees of gearing. For mixer applications, both right-angle and parallel-shaft reducers have advantages and disadvantages. Right-angle reducers are typically shorter than parallel-shaft reducers, allowing them to fit better between floors and below roofs. Conversely, right-angle drives obstruct part of the top ot the tank, which can make piping connections difficult. Mounting and adjusting foot-mounted motors may be easier with right-angle drives than with parallel-shaft reducers.

Parallel-shaft gear reducers use one or more sets of parallel-shaft gears, such as helical gears, to make the necessary speed reduction. Some parallel-shaft reducers have the motor stacked above the worm gear motor to limit the overall diameter of the mixer drive system. Other parallel-shaft reducers have the motor mounted alongside the gear reducer to limit the overall height of th drive system. Generally, parallel-shaft reducers are easier than right-angle mixer drives to design and build. However, they do involve mounting and operating a verical electric motor, which can cause additional problems with large motors.

In-line reducers are usually a variation on parallel-shaft reducers. A properly designed double-reduction reducer with two sets of gearing having the same center distance can be arranged so that the input and output shafts are not only parallel, but in line with one another. Compared with parallel shaft reducers, in-line reducers usually trade greater height for smaller diameter and centered weight. Other types of gearing, such as plaetary planetary gear box, can make an in-line reducer. Whatever the basic configuration, well-designed gear reducers will provide good service in mixer applications.

Right-angle gear reducers must use at least one right-angle gear set, typically spiral bevel or worm gears. Both spiral-bevel and worm gears have unique advantages with respect to mixer applications. Spiral-bevel gears are some of the quietest and most efficient right-angle gears. Although less efficient than other gears, worm gears can make heat dissipation more difficult.
