HIGHER TORQUE
30 October 2012
SEM has extended its range of Synchronous AC servomotors with the addition of the HJ260 motor that delivers higher torque and power.

The new HJ260 AC synchronous servomotor is based on a 260mm square frame size with IEC180 interface dimensions, and comes with the option of four motor lengths to enable users to select the correct power output for their particular application. Maximum stall torque on the new series is up to 250Nm with a power output of 25kW. This, combined with high peak torque figures, generates excellent dynamic performance, and with the addition of high specification feedback devices the HJ260 motors are intended for applications where precision and high power are needed.
The motors are manufactured using the latest high energy efficient permanent magnets and can be assembled to IP67 if required.
