AC Servomotors with PM of the series 5NK

Servomotors of 5NK series are designed for electric drives with speed regulation in the range at least 1:1000 and with high uniformity of running at low speed. Powering of servomotors from frequency converters, attached to single-phase or three-phase network of different voltages 115, 230,400 V etc.

Motors with rugged aluminium frame and connectors on the upper side have stator with three-phase winding and rotor with rare earths permanent magnets. They are equipped with built-in resolver of Czech production and with signal connector (12 pins). Current inlets are connected to main connector (8 pins). PTC termistors in winding.

Smaller sizes 5NK 037 and 5NK 050 cover the stall torques from 0,1 to 0,8 Nm. Driving mains voltage 1 x 230 V, (3 x 400 V if required).

Bigger motors 5NK 076 to 5NK 142 have stall torques from 0,65 to 22 Nm. Driving mains voltage 1 x 230 V or 3 x 400 V.

Maximum mechanical speed 9000 min-1 at smaller sizes and 6000 min-1 at bigger sizes (on demand up to 9000 min-1).
