Product Description:

The MSK100B-0300-NN-S1-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts sinusoidal drive current into controlled rotary motion for indexing tables, pick-and-place units, and other automated motion axes. The motor is intended for applications that require precise positioning, controlled speed changes, and stable repeatability during continuous machine cycles. Integrated feedback allows the connected drive to monitor rotor angle continuously, which helps maintain accurate motion during acceleration, dwell, and reversal. That operating concept suits packaging equipment, transfer systems, and handling modules where compact installation and consistent axis response are both important.

Its thermal management relies on natural convection, so the aluminum housing sheds heat without fans or liquid lines. The motor uses the standard design variant, keeping the mounting interface consistent with other MSK100 models. Rotor position is measured by an encoder that communicates through the Hiperface protocol, allowing the drive to receive absolute angle information and electronic nameplate data over a serial link. An optical sensor reads a disk with 128 signal periods, and the controller interpolates those signals for smooth commutation and stable low-speed operation. The single-turn feedback system reports the shaft position within one mechanical revolution, which is suitable for axes that complete a reference routine before normal production starts.

The motor uses winding set 0300, which matches the electrical characteristics expected by compatible IndraDrive controllers. Power leads exit on the B-side, which can simplify routing where cables must stay clear of adjacent machine elements. The 100 frame size uses a medium housing format, while length B increases the active motor length without changing the basic mounting pattern. A plain shaft supports clamp or collet couplings with low runout, and the motor is supplied without a holding brake, so position retention during power-off conditions must be provided by the machine or the drive system. This arrangement is suitable for axes that do not require a built-in mechanical holding function at standstill.
