Product Description:
The MSK040C-0450-NN-S2-UG1-NNNN is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This compact synchronous servo motor is used for position and speed regulation on automated pick-and-place units, packaging stations, and semiconductor tools. Its standard design and winding code 0450 support precise torque production while remaining compatible with IndraDrive servo amplifiers. The motor is intended for applications that require repeatable motion, stable closed-loop control, and quick response during frequent start-stop cycles.
Heat dissipation relies on natural convection, eliminating auxiliary blowers and simplifying cabinet layouts. An IP65 enclosure guards the stator and bearings against dust and water jets during machine-side installation. Size 040 with length C sets the active core dimensions, and the class 155 insulation system supports continuous winding temperatures up to 155 °C. Rotor position is monitored by an EnDat2.1 feedback interface that provides absolute digital data. Inside the encoder, an optical scanning head resolves 2048 signal periods per revolution, and its 240° rotatable connector allows flexible cable routing in tight electrical spaces. This feedback arrangement supports accurate commutation and position tracking throughout normal servo operation.
An electrically released brake supplies 4 Nm of static holding torque for vertical axes and emergency stops. Power is transmitted through a plain shaft that mates directly with zero-backlash couplings. The feedback system operates in single-turn mode, giving absolute position within one mechanical revolution. Continuous operation is permitted at ambient temperatures from 0–40 °C, which suits typical indoor industrial conditions. This combination supports controlled stopping behavior and direct mechanical integration where compact servo axes need reliable holding and restart performance.
