Product Description:
The MSK070E-0300-NN-M1-UP1-NSNN synchronous servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy from an IndraDrive inverter into controlled rotary motion for indexing tables, pick-and-place units, and coordinated multi-axis machinery. A built-in optical encoder reports absolute shaft position at startup, so the controller can track rotor position immediately after power is restored. This arrangement supports accurate positioning without external transducers and reduces the need for separate feedback hardware on the axis.
Heat is removed through natural convection, so the housing only needs surrounding airflow and no separate fan wiring. The die-cast enclosure carries an IP65 rating, which helps keep dust and low-pressure water jets away from the internal windings during normal industrial use. A factory-installed, spring-applied holding brake keeps the shaft locked when power is absent, and the brake provides 23 Nm of static torque for vertical axes or applications that must resist drift at standstill. Power is transmitted through a shaft with keyway, which supports positive torque transfer to pulleys, couplings, or geared elements.
The feedback system communicates over Hiperface and produces 128 signal periods per mechanical revolution, allowing the drive to receive precise position information for closed-loop operation. Its multiturn capability preserves turn information without a battery, which simplifies operation after power interruptions and reduces dependence on external reference moves. The motor is intended for ambient temperatures from 0 to 40 °C and uses an insulation rating of 155, supporting continuous operation within normal control-room conditions when the motor is mounted correctly. A rotatable 240° connector helps route the feedback cable around nearby machine elements, while frame size 070, motor length E, and winding code 0300 describe the motor configuration used with matching IndraDrive controllers.
