Three-phase asynchronous motor with slip-ring rotor for intermittent duty

The SPER/S11R series are designed as classic IEC/DIN series, i.e. with mounting dimensions and performances in line with DIN 42679. The SPR/S10R series are conceived with more progressive performance assignments compared to the DIN standards, offering outputs up to two steps higher from the same frame size. The motors are equipped with radial fans in plastic or cast aluminium alloy, which cool the motor independently of the latter’s direction of rotation (IC 411 to IEC/EN 60034-6). Upon request, the following motor protection variants are possible: › motor protection with PTC thermistor sensors in the stator winding › bi-metal temperature sensors as NC and NO contacts in the stator winding › resistance thermometer for winding or bearing tem-perature monitoring › space heater to prevent the formation of condensation inside the motor.
