Product Description:

The MSK101E-0450-FN-S1-AG0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As a brushless AC motor, it delivers controlled torque and precise angular positioning for CNC equipment, pick-and-place lines, and other automated machinery that relies on fast dynamic response and closed-loop servo control. Its synchronous operating principle supports accurate rotor control during both positioning moves and steady-speed operation. The motor can also support rapid reversal and short cycle times in automated equipment.

Thermal energy is removed by liquid cooling, permitting continuous torque production at elevated current densities while keeping stator temperatures stable. The housing is sealed to IP65, which keeps out dust and low-pressure water jets so the motor can be mounted outside sealed cabinets. The motor uses size 101 with length code E, giving it a larger frame for demanding servo axes while staying within the MSK mounting format. All phase conductors exit through an A-side power connector, which keeps cable routing on one machine face and helps when the motor is installed close to guarding or machine frames. The integrated feedback assembly communicates through the Hiperface interface, and its optical encoder disc provides 128 signal periods per revolution for accurate position feedback and stable velocity control.

The encoder is single-turn, so absolute shaft angle is retained within one mechanical revolution, which suits indexing applications that do not need multi-turn data. A plain shaft without a keyway supports clamp couplings or shrink discs that transfer torque without the play associated with keyed joints. Insulation class 155 supports higher winding temperatures during cyclic loading, and the motor maintains rated output in ambient conditions from 0 to 40 °C when the coolant circuit remains within its required operating range. The motor is supplied without a holding brake, so the axis must rely on drive torque or an external clamping device when power is removed. On vertical or suspended loads, a separate holding method is required.
