The high-quality medium-voltage motors can be supplied with temperature monitoring for winding and bearings, e.g., 6 x Pt100, resistance thermometers in the stator windings as well as 2 x Pt100 resistance thermometers in the A + B side bearings. The connection terminals of the thermometers are designed in a separate terminal box. In addition, a wide range of further sensors can be supplied if required. The motors are mainly supplied with a standstill heater.
