Stepper motor device with compensating non-sinusoidal driving values and method of producing the driving values |
摘要 |
A stepper motor device uses compensating non-sinusoidal driving values to compensate for operational non-sinusoidal drive characteristics of a motor of the device due to at least design and manufacturing imperfections in the motor. The compensating non-sinusoidal driving values may be derived using back electromagnetic force produced from the motor or using measured rotational positions of the motor when the motor is driven using known driving values.
