Product Description:

The MSK070E-0150-NN-M2-UP0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies precisely regulated torque and speed to automated machine axes in packaging lines, material-handling systems, and machining centers where repeatable positioning and fast dynamic response are required. When paired with a compatible drive controller, the motor converts electrical commands into controlled rotary motion for positioning and speed regulation. This type of motor is suited to closed-loop motion systems that need accurate acceleration, deceleration, and stable speed holding during repeated production cycles.

The unit relies on natural convection for cooling, so no external blower or liquid circuit is required to remove winding heat. Its housing carries an IP65 rating that helps protect internal components from dust and low-pressure water jets on the factory floor. Position feedback is provided by an optical encoder with 2048 signal periods per revolution, and the serial EnDat2.1 interface transfers that data to the drive with good noise immunity. The encoder is a multiturn absolute device, so the controller retains shaft position across 4096 turns after power-up and can avoid a homing cycle. High-resolution feedback also supports accurate commutation and responsive axis control during changing load conditions.

The feedback connector can be rotated through 240°, which helps route cables in tight machine spaces, and the motor is intended for continuous operation in ambient temperatures from 0–40 °C without derating. Mechanical power is delivered through a shaft with a keyway, which helps pulleys or couplings resist slip under load. Insulation in thermal class 155 allows the windings to operate at elevated temperatures, while the E-length rotor and 070 frame support the motor’s intended duty. The design also uses increased concentricity to reduce radial runout, and the motor is supplied without a holding brake, so vertical loads require external braking or drive-generated holding torque during shutdown.
