Product Description:

The MSK071E-0450-NN-M1-UP0-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Within an automated cell it provides closed-loop rotational positioning and speed control when paired with an IndraDrive amplifier, allowing equipment builders to integrate accurate motion for pick-place heads, conveyors, or indexing tables.

Its cooling concept uses natural convection, so heat leaves the housing through surface radiation and ambient air without fans or liquid loops. The electromagnetic profile is defined by winding code 0450, which sets voltage and current values compatible with standard IndraDrive modules. Position feedback travels over the Hiperface serial interface that carries absolute data and drive parameters on two shielded conductors. Inside the encoder, an optical reader scans a glass scale with 128 signal periods per revolution, and non-volatile tracking of multiple turns is handled by multiturn absolute electronics that need no gears. Together these features deliver high-resolution velocity loops and remove the need for homing after power cycles.

Mechanical integration is simplified by the rotatable, 240° connector that lets the feedback cable exit in different directions to match cabinet layouts. The frame code 071 establishes the mounting face and pilot diameter common to mid-size machines, while length code E indicates a deeper lamination stack that increases torque without changing the footprint. Power is transferred through a shaft with keyway, allowing the motor to couple directly to pulleys or gearboxes using standard keyed hubs. Because the design is standard and supplied without a holding brake, static load retention must be handled by the drive’s torque or an external clamp. All elements—from the passive cooling surface to the feedback electronics—work together so the axis can meet duty requirements without auxiliary fans or frequent maintenance.
