Product Description:

The MSM020B-0300-NN-M0-CG1 is a synchronous motor from the MSM IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. The unit converts electrical energy into controlled rotary motion for tasks such as pick-and-place heads, small indexing tables, or auxiliary conveyor drives where precise position control and compact size are required within industrial automation cells.

The motor includes an Electrical Release holding brake that engages automatically when supply voltage is removed; during energized operation it supplies 0.29 Nm of static torque to keep the shaft locked. Stator heat is dissipated by Natural convection, allowing installation inside enclosed panels without additional fans. Power and feedback exit the housing through a molded cable tail that maintains sealing and eases routing toward the drive. Rotor position information is generated by a Multiturn Absolute encoder, so the controller always knows the mechanical angle after power-up without a reference move. Electromagnetic characteristics are defined by winding code 0300, which matches the resistance and inductance expected by Rexroth low-voltage servo amplifiers and determines the continuous current limit for this frame.

For mechanical integration, the frame corresponds to size 020 with length code B, giving an overall body length of roughly 70 mm and a flange pattern that fits standardized adapter plates. The compact lamination stack reduces mass, improving dynamic cycle times when the axis must start, stop, or reverse in quick succession. Passive cooling keeps surface temperature within permissible limits, and the potted internals resist shock common on assembly machinery. Built by Bosch Rexroth Indramat, the motor belongs to the MSM IndraDyn S family, enabling direct parameter sets in Rexroth drive firmware and minimizing commissioning effort.
