Product Description:

The MSK100B-0450-NN-S2-BP0-RNNN is a three-phase synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor serves as the drive element in automated handling systems, gantry axes, and high-speed machining spindles where precise torque control and repeatable positioning are required. Integrated feedback and a keyed shaft let the unit transmit motion directly to gearboxes or couplings, making it a common choice for industrial automation systems that need compact dimensions and responsive motion control. The motor can also be used on rotary axes that require fast response during start, stop, and reversal.

Heat is removed by natural convection, so the housing relies on ambient airflow rather than forced fans. For reliable cooling, the machine should leave open space around the motor surface. Position data are transmitted through the EnDat2.1 serial interface, allowing digital feedback with parameter storage and error checking. Digital feedback also helps the controller maintain stable commutation across the speed range. The encoder is optical and single-turn with 2048 signal periods, which supports smooth velocity control and accurate position tracking. The housing is sealed to IP65, and continuous operation is limited to an ambient range of 0 to 40 °C.

The motor has a frame code of 100 and a stack length code of B, which correspond to its flange size and active iron length. Power connections exit on side B, and a shaft with keyway provides slip-free torque transfer to pulleys or couplings. This arrangement supports direct coupling to common machine elements without adding separate transmission components. Because the motor is supplied without a holding brake, any vertical load must be held by drive torque or an external brake when power is removed. Insulation class 155 supports high winding temperatures during operation, and winding code 0450 matches the electrical characteristics expected by compatible IndraDrive controllers.
