Product Description:
The MSK070E-0300-NN-S1-BG0-NNAN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit converts drive current from a compatible controller into precise rotary motion for positioning tables, gantry axes, and packaging equipment. It is intended for closed-loop axes that need accurate positioning, stable speed control, and repeatable motion during frequent starts and stops. The motor can be used in packaging, handling, and indexing equipment where compact rotary actuation is required.
This servo motor dissipates heat through natural convection, so no external blower or liquid circuit is required for continuous duty at its rated load. A reduced runout mechanical design limits shaft radial error and helps protect feedback quality when the motor is connected to precision couplings. Rotor position is reported over the Hiperface serial interface, allowing a two-wire hybrid cable to carry power and data to the controller. Inside the encoder, an optical scanning head resolves the code disk into 128 signal periods, which gives the drive fine commutation resolution for smooth velocity control. This feedback arrangement also supports steady motion through acceleration changes and short positioning moves.
The feedback element is a single-turn device, so absolute position is retained within one mechanical revolution, which suits cyclic indexing stations and similar repetitive axes. With a frame outside diameter classified as motor size 070, the motor fits mid-range machine envelopes while delivering more torque than smaller MSK frames. Power conductors exit on side B of the housing, and the motor uses a plain shaft for couplings or gearboxes that clamp externally. The unit is supplied without a holding brake, so braking torque must be provided by the drive or an external brake when standstill holding is required. Its construction uses motor length E and winding code 0300, which gives a practical balance of speed and thermal capacity for general automation duty.
