Product Description:

The MSM019B-0300-NN-M5-ML0 is a compact rotary actuator manufactured by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. It converts electrical input from a compatible drive into synchronized mechanical rotation for indexing tables, pick-and-place arms, and other low-torque axes in automated cells. The small frame is intended for installations where available space is restricted but accurate positioning is still required. In these applications, the actuator supports precise rotary movement where a larger motor would take unnecessary space or add excess mass to the mechanism. It is well suited to rotary tasks that cycle frequently and must return to the same position.

At standstill the rotor can deliver a continuous torque of 0.32 Nm, which is the maximum load it can hold indefinitely without thermal overload. Heat produced at this operating point is removed through natural convection, so the motor relies on free airflow rather than forced cooling hardware. Because the unit is supplied without a holding brake, any static position must be maintained by drive current or an external mechanical lock. The frame is classified as Motor size 019, which places it in the smallest mounting pattern in the MSM range. Its compact footprint helps it fit tightly spaced axes in automated equipment.

The electrical layout identified by winding code 0300 sets phase characteristics that match the compact stator and support quick response when the drive issues rapid speed commands. The motor has a motor length B housing, so the active stack is longer without enlarging the flange. That gives the actuator moderate inertia for smoother motion during intermittent duty cycles. It is intended for low-torque positioning axes in compact machine modules, where controlled starts and repeatable motion are more important than high output force.
