Product Description:

The MSM020B-0300-NN-C0-CG0 is a small-frame synchronous motor used on light-duty positioning axes, pick-and-place heads, and auxiliary feeds that need compact dimensions in industrial automation. The housing couples directly to IndraDrive controllers, and an internal sensor allows the drive to close the motion loop without external feedback hardware. This arrangement keeps the axis compact because separate feedback devices and extra mounting space are not required. Its small size also suits mechanisms where low moving mass helps maintain responsive motion. Because the motor is intended for smaller axes, it is well suited to repetitive indexing and short travel tasks where package size matters as much as torque.

The motor removes internally generated heat to the surrounding air through natural convection, so it can be mounted in tight cabinets without forced-air devices. Power, feedback, and protective earth conductors exit the stator on a cable tail, which simplifies routing in moving machine sections and reduces the clearance needed around the motor body. Rotor position is delivered by an incremental encoder, providing cyclic signals that the controller interpolates for speed and position regulation. The unit is supplied without a holding brake, making it better suited for horizontal axes or mechanisms that rely on drive torque to hold position during a power-off event. Overall depth follows the B length code, giving the motor a medium body size that balances torque output against restricted installation space. That body length also leaves room for couplings and nearby guards without making the assembly unnecessarily long.

With a frame designation of 020, the stator diameter stays small, allowing several motors to be stacked side by side on compact machinery. The electromagnetic package identified by winding code 0300 sets the coil impedance and nominal current used by the matching drive amplifier. This combination helps the motor fit small servo axes that need predictable current matching with the drive. The narrow stator envelope is useful on transfer units and other compact machine sections where multiple actuators sit close together. It belongs to the MSM IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat.
