Product Description:
The MSK061B-0300-NN-M3-UP0-NNNN synchronous motor is built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Classified as a standard B-length unit within the 061 frame group, it is intended for servo axes that call for direct-drive precision in packaging lines, robotics, and material handling equipment. By converting controlled current from an IndraDrive amplifier into rotational motion, the motor delivers closed-loop positioning and velocity control that supports coordinated, repeatable automation cycles. Its synchronous design supports precise starts, stops, and speed transitions in machines that depend on predictable axis behavior.
Thermal regulation is handled by natural convection, eliminating the need for external fans and allowing cabinet installation with minimal maintenance. Feedback to the drive uses a Hiperface digital interface through a rotatable 240° hybrid connector, which eases cable routing in tight panels. Inside the encoder housing, a capacitive scanning system generates 16 signal periods per mechanical revolution. This arrangement is resistant to oil vapor and magnetic debris, and it retains position data over power cycles through its multi-turn absolute functionality. Winding code 0300 aligns the resistance and inductance values with companion IndraDrive controllers, enabling repeatable torque production across the speed range.
For plant reliability, the housing carries an IP65 protection rating, and continuous service is supported within an ambient range of 0 to 40 °C without derating. Mechanical power exits through a shaft with a keyway, simplifying coupling alignment, while Class 155 insulation helps protect the windings during cyclic loads. Because the unit is supplied without a holding brake, external holding force is required when vertical or suspended loads must remain in place. The encoder retains position data after power loss, so axes can resume commanded motion immediately on restart.
