Product Description:

The MSK040C-0600-NN-S1-UG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts controlled three-phase power from an IndraDrive amplifier into accurate rotary motion that positions actuators, indexing tables, or conveyor segments. Compact geometry and integrated feedback make the unit suited for tightly packaged automation where precise speed, torque, and position loops are required. Its synchronous design also supports repeatable motion on short-cycle axes that need fast response to changing commands.

The motor uses frame size 040, giving a 47 mm stator diameter that fits small machines while delivering usable torque. A length code C lamination stack extends magnetic surface for higher continuous output. The electromagnetic circuit follows winding code 0600, so voltage constant and current demand match mid-range IndraDrive converters. Cooling is through natural convection, allowing cabinet mounting without ducted air. Heat dissipates across the motor surface, which helps maintain stable operation during continuous duty. A plain shaft simplifies coupling selection because no keyway fixes the mounting orientation. This shaft style is often used with clamp couplings in compact drive trains, and the cooling method avoids auxiliary fan hardware on the motor body.

The feedback assembly communicates over a Hiperface interface, letting the drive exchange identification and calibration data. Its optical sensor generates 128 signal periods per revolution, which the control interpolates for fine position information. The measurement span is single-turn, so absolute data is retained for one revolution and suits axes with limited travel. The motor is supplied without a holding brake, so vertical loads require drive torque or an external clamp when power is removed. Omitting the brake also reduces added inertia at the shaft, which can help preserve quick response in light moving systems.
