Computer Simulation of Process of Sensorless Determination of Dynamic Signals in Stepping Motors

Bodnicki M., Pochanke A.

Machine Dynamics Problems

2006

Vol. 30, No. 3

51-57

A new ideas of control and testing of miniature electric motors was developed by authors. The possibility of determination of the electromagnetic torque generated by stepping motor, carried on during its work, is analysed. The indirect methods without additional mechanical transducers are proposed. The simulation model of the work of stepping motor is used in analysis. Two methods are taken into consideration. The first method follows direct from equations of the voltage balance in the motor coils. The second one based on knowledge of the courses of the induced voltages of the rotation, determined by the constant angular velocity of the rotor. The simulation tests confirm utility of both methods.
