Rewindable motor MS series
2-pole induction motor, 50 Hz (n ≈ 2900 rpm).
Sized for connection to the pumps according to NEMA Standards.
Standard voltages:
– single-phase 230 V up to 2,2 kW for 4” motors.
– three-phase 230 V; 400 V, for 4” motors.
– three-phase 400 V; 400/690 V, for 6” motors.
Voltage tolerance : +6% / -10%.
In order to limit both current and torque at each starting, for rated motor powers equal to or higher than 7.5 kW, one of the following types of starting is necessary: star/delta, soft starter, stator impedance or autotransformer.
Special features on request:
– Other voltages.
– 60 Hz frequency.
– Other temperatures.
