Product Description:
The MSK101D-0450-NN-M2-AG3-RNNN synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Serving as a compact drive element, it converts electrical energy into controlled mechanical rotation for positioning tables, gantries, and packaging equipment. The unit’s size 101 stator and D-length stack provide the torque capacity needed for mid-range servo axes, while the design minimizes runout so feedback devices remain aligned during continuous industrial duty.
The motor dissipates heat through natural convection, eliminating the need for auxiliary fans and allowing installation in tight enclosures. Its increased concentricity construction keeps the rotor precisely centered, which reduces vibration transmitted to connected mechanics. Position feedback is generated by an optical encoder that communicates over the EnDat2.1 serial link, and the sensing head resolves 2048 signal periods with low interpolation error. Multi-turn absolute capability lets the control system read the shaft location after power is restored without external homing. Electrical terminations are routed through a power connector on the A-side of the housing, which simplifies cable runs in multi-axis assemblies. The winding code 0450 pairs the motor with compatible IndraDrive servo amplifiers.
For safety on idle or vertically loaded axes, the motor is delivered with a holding brake that is electrically released and produces 120 Nm of static torque. The housing is sealed to IP65, which keeps dust and low-pressure water jets away from the windings and the plain shaft while supporting direct exposure on machine frames. Thermal endurance is class 155, so the insulation remains stable up to that winding temperature. The specified ambient range is 0 to 40 °C, which helps prevent excessive surface heating.
