Drive, has sensor comprising electronic circuit galvanically connected with intermediate circuit potential of intermediate circuit voltage with connection of intermediate circuit condenser or intermediate circuit capacitor

摘要

The drive has a converter-fed electric motor (M), and a rotary sensor (D) i.e. rotary encoder, arranged at the motor for detecting angular position of a shaft i.e. driveshaft, of the motor. Converter signal electronics comprises a controller, and power electronics comprises an inverter fed by an intermediate circuit voltage (U). The sensor comprises an electronic circuit galvanically connected with an intermediate circuit potential of the intermediate circuit voltage with one of the connection of an intermediate circuit condenser (Z) or an intermediate circuit capacitor.
