Product Description:

The MSK101D-0450-FN-S1-BP0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts controlled drive current into torque for axes that must accelerate, decelerate, and position rapidly within industrial automation cells and machine tools. The motor occupies the size 101 frame with length code D, giving it a compact high-torque profile suitable for multi-axis gantries, packaging equipment, and metal-cutting applications. Its operating role is to deliver repeatable rotary motion where short cycle times, accurate path control, and consistent response are important.

Thermal management is handled by liquid cooling, allowing continuous high-load operation without derating. Feedback comes from a Hiperface optical encoder that provides 128 signal periods per mechanical revolution, delivering fine resolution for velocity and position loops while using a two-wire serial channel. The encoder is single-turn, so absolute position is retained within one revolution and the drive can track rotor movement directly during startup and normal operation. Mechanical design includes a shaft with a keyway, enabling positive torque transfer to couplings or pulleys. The housing carries an IP65 rating, sealing the stator against dust and water jets. The power connector sits on the B-side, matching the orientation used on this motor length.

The motor is specified for ambient temperatures from 0 to 40 °C, matching typical control cabinet climates in automated lines. Its windings follow insulation class 155, so copper conductors and varnish withstand elevated temperatures generated during sustained duty cycles. Electromagnetic behavior uses winding code 0450, which corresponds to the resistance, inductance, and back-EMF expected by Rexroth drive amplifiers. The unit is supplied without a holding brake, which suits axes that rely on external clamping devices, counterbalances, or drive torque for position retention. In installations that stop under external mechanical restraint, the absence of an internal brake can also reduce the number of components inside the motor.
