Product Description:

The MSK070D-0450-NN-M1-UP0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S unit, the motor is intended for high-precision torque and position control in automated machinery such as packaging modules, pick-and-place axes, and printing rollers. Its electronic commutation and permanent-magnet rotor enable fast response without sacrificing accuracy, allowing the motor to integrate directly with Rexroth drive controllers in closed-loop motion platforms. Its compact power density suits mounting inside distributed servo modules.

The motor housing follows a standard design and is cooled by natural convection, so excess heat is removed through surface radiation and airflow without auxiliary fans. Feedback is managed through a rotatable Hiperface connector with 240° rotation to ease cable routing in tight cabinets. Inside the encoder, an optical scanning system delivers position data with 128 signal periods, giving the drive enough resolution for smooth velocity regulation. The absence of a holding brake reduces overall length and inertia, while the D-coded motor length balances torque capability with installation depth.

Position memory across power cycles is provided by the multiturn absolute encoder, allowing the controller to recover axis coordinates without homing. Mechanical power is transmitted through a shaft with a keyway, giving positive torque transfer to pulleys or couplings. The MSK winding group identified by 0450 indicates the wire gauge and turns per phase, which determine the current constant required by the matching drive. Size code 070 indicates the stator diameter, which affects the mounting bolt circle and supports higher corner torques than smaller MSK frames. These values help match the motor to gear ratios, drive currents, and positional accuracy targets in multi-axis production lines.
