N a generator driven by an electric motor, by means of which the voltage, frequency, or phases of an electrical power supply can be changed 电动发电机
In general, tachometer generators are eliminated in the small and medium power DC rotating speed governing systems, and armature voltage is used as motor speed signal.
在中小型直流调速系统中，一般都取消了测速发电机，而以电枢电压作为电机转速信号。
Because the power is limited by the circulation pressure, therefor use the motor pump as the power of hydraulic, the power of the motor pump supply from the turbine generators underground.
由于动力源受制于环空压差，所以采用电机泵作为液压动力，电机泵由井下涡轮发电机供电。
These include sensory reception, reflex arcs, spinal cord organization, pattern generators, muscle function, locomotion, eye movement, and cognitive aspects of motor control.
