Product Description:
The MSM019B-R300-NN-M0-CH1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. In automated assembly cells, pick-and-place gantries, and lightweight handling axes, this unit converts drive current into controlled rotary motion for accurate positioning. Integrated position feedback and a holding brake allow the motor to keep an axis stationary when power is removed. This makes the unit suitable for compact motion tasks where repeatable movement and stable stopping behavior are required.
At standstill, the motor can deliver 0.32 Nm of continuous torque without exceeding its thermal limits. Heat in this operating condition is dissipated by natural convection, so no external fan or coolant lines are required when airflow around the frame remains unobstructed. Shaft position is tracked by a multi-turn absolute encoder, allowing the controller to retain position information over multiple mechanical turns after a power loss. The brake is an electrically released brake; spring force clamps the rotor when the coil is de-energized, and the brake releases only when current is applied. The stator uses winding code R300, which matches the voltage and current ranges used by compatible IndraDrive servo amplifiers.
The brake provides up to 0.29 Nm of static holding torque, which helps secure vertical or overhung loads when the axis is not being driven. Power and feedback conductors leave the housing through a cable tail, which helps routing in compact cable chains and confined installation spaces. With frame size 019 and length code B, the motor fits applications where installation space is limited near sensors, grippers, or other moving components. The motor uses a plain steel shaft without keyways, and it does not include a shaft seal, so it is best suited for protected enclosures where dust and fluids are controlled. Its synchronous design supports accurate low-speed positioning in indexing tables and small actuators.
