Bosch Rexroth MSK070C-0150-NN-S1-UG0-NNNN Servo Motor

In stock

Thirteen newton metres of standstill torque from an 11.7 kg frame is the headline of the MSK070C-0150, a Bosch Rexroth IndraDyn S synchronous servo motor with winding 0150 and a 2,500 min-1 maximum speed. At 60 K it delivers 13 Nm at 4.1 A, at 100 K 14.5 Nm at 4.6 A, and 33 Nm peak at 16.4 A maximum current. Rotor inertia is 0.00291 kgm². The S1 option is an optical singleturn absolute Hiperface encoder with 128 signal periods, housed under IP65 protection.

1️⃣Overview

The MSK070C-0150-NN-S1-UG0-NNNN is a permanent-magnet synchronous servo motor from the Bosch Rexroth IndraDyn S MSK range, built for high torque density in a compact frame. It combines frame size 070 with frame length C and winding 0150, giving 13 Nm standstill torque at natural convection cooling and a maximum torque of 33 Nm for acceleration peaks. The motor carries a singleturn absolute optical encoder with Hiperface interface and 128 signal periods, a smooth shaft with shaft sealing ring, no holding brake, and an IP65 housing. With a mass of only 11.7 kg and a rotor moment of inertia of 0.00291 kgm², it is a direct replacement motor for compact machine axes in packaging, printing, handling and machine tool applications.
