Product Description:

The MSK070E-0450-NN-M2-UG0-RNNN synchronous servo motor is manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This brushless AC unit converts controller commands into precise rotary motion for positioning tables, pick-and-place heads, and other automated axes. As part of an IndraDrive system, it offers high dynamic performance while remaining compact for machine frames.

Thermal management relies on natural convection, so heat leaves the housing without fans, reducing upkeep. The stator uses winding code 0450, which sets the current-to-voltage ratio for compatibility with IndraDrive power stages. With frame size 070, the motor’s mounting face and shaft dimensions fit medium-load actuators. Position data are transmitted over the digital EnDat2.1 interface, allowing single-cable feedback when the drive supports hybrid wiring. Inside the feedback assembly, an optical sensor resolves 2048 signal periods per revolution, giving the controller fine commutation increments and very precise position information. The motor is built without a holding brake, so a static load must be secured by drive torque or external clamps. Its length class E extends the lamination stack, increasing continuous torque compared with shorter bodies.

The integrated encoder uses multiturn absolute counting, reporting both turn count and fine angle so homing is not required after power loss. Its cable entry is a rotatable, 240° connector that can be positioned to ease routing inside tight enclosures. The motor has an increased concentricity design for the rotor and flange; this reduces radial runout and helps maintain uniform air gaps at high speed. A plain shaft transmits torque without a key, which benefits applications that rely on shrink-fit or clamp couplings and need minimal backlash. Optical scanning technology inside the encoder and the absence of fans help limit mechanical wear during continuous duty.
