Product Description:

The MSK101E-0300-FN-M1-RG3-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. This model combines the electromagnetic design of the 101 frame size with the E length code to supply controlled torque and speed for positioning axes, packaging equipment, and transfer modules. Within an automation cell, it serves as the electromechanical actuator that translates drive controller commands into precise rotary motion for consistent process accuracy. Its synchronous design also supports repeatable response during rapid starts, stops, and reversing moves on axes that must track programmed motion without drift.

Heat generated in the stator is removed through liquid cooling, allowing the motor to deliver rated performance with reduced enclosure temperatures and tighter cabinet layouts. Winding code 0300 identifies the stator’s electrical profile, and the E length accommodates extra active material for higher stall torque. Position feedback travels over the Hiperface interface, so the drive receives both absolute position and real-time velocity data on a single bidirectional channel. The optical encoder yields 128 signal periods per revolution, supporting fine interpolation for smooth low-speed movement. This feedback arrangement helps the controller maintain stable commutation and consistent motion through acceleration and low-speed holding. An electrically released holding brake supplies 120 Nm of torque, maintaining axis position during power-off or safety stops.

The housing carries an IP65 rating, sealing the windings against dust ingress and water jets encountered on factory floors. Continuous operation is specified for ambient ranges of 0–40 °C, so no derating is required inside typical climate-controlled machines. Power enters through a right-side connector that streamlines cable routing along machine frames and can reduce cable bending near the motor body where space is limited. A plain shaft simplifies coupling to gearboxes or direct-drive loads, and wire insulation meets class 155 thermal requirements for sustained motor operation under load. The insulation system supports elevated internal temperatures associated with continuous servo operation.
