Product Description:

The MSM020B-0300-NN-C0-CG1 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. In automated assembly stations and light handling axes, the unit converts drive current from an IndraDrive amplifier into controlled rotary motion that can be coordinated with position feedback from its integrated encoder. Its compact size makes it suitable for grippers, indexing tables, and miniature transfer mechanisms where moving mass must be kept low. The motor is intended for applications that need accurate starts, stops, and repeatable motion in a limited installation space.

Its brake uses electrical release, which means the spring-applied brake stays engaged until voltage is applied to open it. Combined with a holding torque of 0.29 Nm, the brake can hold low-inertia loads during power-off conditions or emergency stops. Heat generated in continuous duty is dissipated by natural convection, so no external fan is required. Power, brake, and feedback conductors leave the housing through a cable tail, which works well in sealed cabinets where fixed cable routing is preferred. Rotor position is detected by an incremental encoder, giving the drive cyclic pulses for speed and position control. This feedback arrangement supports smooth low-speed operation and stable response during frequent direction changes.

The motor uses frame size 020, and the stack length code B keeps the active core short to reduce mass during high-acceleration moves. Winding code 0300 indicates the electrical values used by the drive for current setup and transient torque behavior. The short active length also helps keep the housing compact where clearance around tooling and fixtures is limited. The motor shares the same general mounting and shaft layout used across comparable models in the product line, which supports consistent integration on small servo axes.
