Product Description:
The MSK070E-0300-NN-M2-UP1-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a precision actuator in industrial automation, delivering controlled torque and speed for coordinated multi-axis motion. The motor uses permanent-magnet excitation and winding code 0300 to produce a sinusoidal back EMF profile suited to high-performance drive controllers. With its compact 070 frame and E length, the unit fits into tight machine housings while still providing the dynamic response needed for packaging equipment, pick-and-place systems, and electronic assembly lines.
Heat generated by the stator is removed through natural convection, so the motor does not require forced-air or liquid-cooling hardware. The housing has an IP65 rating, which helps keep dust and low-pressure water jets away from internal components during operation. Position data are sent to the drive through the EnDat 2.1 serial interface, and the integrated optical encoder provides 2048 signal periods for high-resolution interpolation in the controller. Multiturn counting electronics preserve position information after power loss, and an electrically released brake provides 23 Nm of static holding torque to keep the shaft in place when needed.
Improved concentricity at the rotor-to-stator air gap reduces radial force ripple and helps the motor run more smoothly at low speeds. The feedback assembly uses a rotatable 240° connector, which makes cable routing easier when the motor is installed in confined spaces. Encoder sensing relies on optical scanning, and the output uses a shaft with a keyway to transmit torque to pulleys or couplings without slip. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and the insulation system meets class 155 for winding heat resistance under rated load.
