Electronically commutated motor for use with e.g. submersible pump, has magnetic signal transmitter for adjusting number of revolutions of motor, where motor is accommodated together with control electronics for controlling motor in housing

摘要

The motor has a rotor and a stator, where the motor is accommodated together with control electronics for controlling the motor in a pressure-resistant insulated housing (1). A magnetic signal transmitter (6) adjusts the number of revolutions of the motor, where adjusting signals are transmitted to a signal receiver (7) with the help of the transmitter. The signals are evaluated by the circuit electronics and are converted into a number of revolution inputs, where the signal transmitter and the signal receiver are arranged in the housing.
