- 摘要：
- Method for control of synchronous electrical motors with application for stepper and Brush-Less Direct Current motors for which there is an explicit relation between the active electrical power supplied to the motor and the mechanical power that the motor delivers to the load. The active electrical power Pel consumed by the motor is measured and according to FIG. 3 the mechanical power Pmech and the maximum available mechanical power Pmech max are determined. The ratio between Pmech and Pmech max is calculated and is compared to the set value of the same ratio. If it is greater than the set one either the operating currents are increased either the operating speed is decreased or both operations are executed. But if it is smaller—either the operating currents are decreased either the operating speed is increased or both operations are executed.
