Product Description:

The MSK061B-0300-NN-M1-UP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet motor for industrial automation, it converts electrical power from a drive into precisely controlled rotary motion. This supports positioning, contouring, and cyclic tasks on CNC machines and packaging lines. The motor is intended for closed-loop operation with a compatible servo drive, where commanded current is converted into controlled torque and speed at the shaft. Its design suits axes that need repeatable motion during frequent start-stop cycles.

This model uses natural convection for heat dissipation, so airflow around the housing must remain unobstructed during continuous duty. Because cooling is passive, the motor can be installed without auxiliary fan hardware if surrounding air can circulate freely around the housing. An electrically released brake delivers 10 Nm of static torque, allowing an axis to hold position when the drive is disabled. The housing carries an IP65 rating, which protects internal components from dust and low-pressure water jets on industrial equipment. Class 155 winding insulation permits winding temperatures up to 155 °C, and feedback is exchanged over the Hiperface interface so position signals and configuration data can share the same cable.

Position data is provided by an optical encoder that outputs 128 signal periods per revolution, allowing fine interpolation inside the drive controller. The encoder connector can be rotated through 240°, which helps route the cable to suit cabinet layouts and reduce bend stress. Multiturn tracking is available through its Multiturn Absolute design, which records shaft turns even when system power is removed and avoids a homing cycle after startup. Winding code 0300 identifies the electromagnetic design and matches the motor to drives that deliver the corresponding voltage and current profile. Combined with size 061 and length B, this layout suits mid-frame pick-and-place robots and indexing tables within an ambient range of 0 to 40 °C.
