What are the important technical parameters of step motor?
Lost step: the number of steps that the motor is running is not equal to the number of steps in theory. 7), imbalance Angle: the rotor teeth axis offset Angle, the stator tooth axis motor operates will exist imbalance Angle, produced by imbalance Angle error, and adopts subdivision drive can't be solved. 8) performance characteristics: the curve of the output torque and frequency relation of the motor under certain test conditions.
To keep torque: it is the moment when the motor is connected to the motor without turning, the stator holds the torque of the rotor. 4) the step Angle: corresponds to a pulse signal, the angular displacement of the motor rotor.
The phase number of the step motor: the number of coils inside the motor, the two phase, three-phase and five-phase step motor are commonly used. Number of beats: the number of impulses required for a periodic change in a magnetic field, or the state of conduction, in terms of m, or the number of impulses required to turn a tooth from an electric motor.
