摘要
An inverter-fed induction motor and a brushless DC motor are connected to the same control system using open loop or closed control for the motor speeds. The DC (1) and AC sync. (2) motors are brought under r.p.m. regulation from a common control (5) via a lead (3). A rotor position detector is integrated with the AC motor and coupled to the motor control via another electrical lead (6). The detector signals are evaluated to produce the sync. rotary field for the DC motor. A voltage supply (7) and stipulated value setter (8) are connected to the control. ADVANTAGE - Simplified control strategy.
