Product Description:
The MSK071D-0300-NN-M1-UP2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion for positioning axes, feed drives, and coordinated multi-axis equipment in industrial automation cells. The motor works with compatible drive controllers to generate precise torque and speed profiles for material handling, packaging lines, and metal-forming processes. Its compact housing supports installation where accurate motion must be maintained during frequent starts, stops, and speed changes.
The motor relies on natural convection as its cooling method, so thermal energy leaves the housing through surface radiation and ambient airflow without forced fans. Because the design requires free airflow around the housing, the mounting arrangement should not block heat dissipation surfaces. An electrically released holding brake supplies 30 Nm of static torque, locking the shaft during power-off and releasing automatically when current is applied. Position feedback is routed through a rotatable 240-degree connector that carries a Hiperface interface. Inside the encoder, 128 signal periods per revolution are produced by an optical scanning system, helping the drive maintain stable speed control and accurate position tracking.
The encoder operates in multiturn absolute mode, so rotor position remains available across multiple revolutions after startup. Mechanical power is transmitted through a shaft with keyway, which supports secure coupling to pulleys or gearboxes under load. Electromagnetic behavior is set by the winding code 0300, which gives the resistance and inductance values used by matched IndraDrive amplifiers. The motor belongs to the 071 size class with a D-length housing, giving it a compact footprint for its performance range. This layout supports use on axes that need precise acceleration, repeatable stopping behavior, and dependable feedback during continuous machine operation.
