Product Description:

The MSK040B-0600-NN-M1-UP1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. This motor is intended for precision positioning and velocity control in automated machinery where compact dimensions and stable torque output are required. By integrating with electronic drives, it converts electrical command signals into controlled rotary motion for axes on packaging lines, pick-and-place gantries, or general handling stations. Its compact format also suits transfer units and indexing mechanisms where motor size affects axis spacing and moving mass. That makes it suitable for machines that require short travel cycles, frequent reversals, and repeatable motion without oversized mechanical components.

The unit is cooled by passive surface airflow, described as natural convection, so no external fans or liquid circuits are needed. An electrically released holding brake supplies 4 Nm of static torque, securing vertical loads during power loss and helping keep an axis in place at standstill. Position feedback is transmitted over the Hiperface interface, enabling a direct data link between the motor and drive. Inside the feedback assembly, an Optical scanning system works with a Multiturn Absolute encoder to preserve position across power cycles, allowing the controller to recognize rotor angle immediately after startup. This arrangement supports stable closed-loop control during low-speed movement and during repeated stopping and restarting.

Mechanical drive-train coupling uses a shaft with keyway, providing positive torque transfer into pulleys or gearboxes and reducing the chance of slip during repeated acceleration cycles. The encoder delivers 128 signal periods per revolution, giving the drive a fine position reference after interpolation of the sinusoidal signals. This helps the servo system maintain smooth low-speed control and stable commutation during frequent start-stop operation. The motor has a frame size of 040 with length code B, which keeps the housing narrow for use in closely spaced multi-axis assemblies. Winding set 0600 sets the electrical resistance and inductance values expected by compatible IndraDrive controllers, so current response and thermal behavior can be matched to the motor.
