Ripple voltage: AC voltage at the output of DC power supply Number of phases: the number of pairs Blower Motors of excitation coils that produce N and S magnetic fields of different pairs of poles.
Step angle: the angle of rotation when the stepper motor receives the pulse signal Misalignment angle: the angle at which the rotor tooth axis deviates from the stator tooth axis. Static torque: The locking torque of the motor shaft when the motor is not rotating under the action of the rated static voltage.
DETENT TORQUE: The torque at which the stator locks the rotor when the stepper motor is not powered on. The most important parameters of stepper motors: (Caused by harmonics of the magnetic field tooth profile and mechanical errors).
Generally, the torque of a stepping motor at low speed is close to the holding torque. No-load starting frequency: the pulse frequency that can be started normally under no-load conditions. Accuracy: 3%~5% of the step angle without accumulation. Loss of step: the number of running steps when the motor is running is not equal to the theoretical number of steps. This torque is a measure of the volume of the motor, and has nothing to do with the driving voltage and driving power.
DC power supply of the drive: select the voltage according to the speed and response requirements of the motor, but the ripple voltage cannot exceed the maximum input voltage of the drive. Beats: the number of pulses required for the motor to rotate through a pitch angle.
Holding torque: When the stepper motor is energized but not rotating, the stator locks the rotor torque. The power supply current is selected according to the output phase current of the driver
