Product Description:
The MSK070E-0450-NN-M1-UP1-NNNN synchronous servomotor is built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The motor serves as a compact rotary actuator that delivers commanded torque and speed to automated axes in packaging, printing, and material-handling equipment. Its standard construction, integrated feedback, and electrically released holding brake allow the drive controller to position loads accurately while keeping the axis secure when power is removed. It can be used on positioning, indexing, and synchronized transport axes that require repeatable motion during frequent start-stop cycles. The compact housing also suits machine layouts that need servo performance without a large motor envelope.
Cooling relies on natural convection, so heat is dissipated through the housing without auxiliary fans or liquid circuits. This keeps the motor suitable for installations where simple thermal management and quiet operation are preferred. When the machine is idle, the electrically released brake supplies 23 Nm of countertorque, helping prevent vertical or suspended loads from drifting. Rotor position is monitored with a multi-turn absolute encoder, which tracks several revolutions and reduces the need for a return-to-reference move after shutdown. Communication between this encoder and the drive occurs over Hiperface, and measurement uses optical scanning for precise sine-cosine signals in speed and position control.
For flexible cable routing, the feedback connector is rotatable through 240°, letting the plug be turned within the permitted sector to clear nearby machine parts. The encoder provides 128 signal periods per mechanical revolution, giving the drive broad interpolation headroom for smooth motion at low and high speeds. Power is transferred through a shaft with a keyway, which helps the coupling resist slip under changing load conditions. The frame size is 070, placing the motor in a medium-torque format that balances installation space with continuous output in general automation axes.
