Product Description:
The MS2M02-B0FNN-KMDH0 is a servo motor produced by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. This compact rotary unit provides precise position and speed control in automated pick-and-place modules, small conveyors, and packaging spindles. Its high power density supports installation in space-limited machine frames without requiring external gearbox adapters. The motor can be paired with a compatible servo drive to regulate motion under changing speed and load conditions.
Heat generated during operation is removed through natural convection, so no external blower or liquid cooling circuit is required. Position feedback is supplied by a 23-bit optical encoder that can operate in single-turn or multi-turn modes, giving the drive high-resolution rotor angle data. The housing has an IP65 rating, protecting the motor against dust ingress and low-pressure water jets. Continuous service is supported at ambient temperatures from 0 to 40 °C, which covers the typical operating range of industrial machinery. The winding supports a synchronous speed of 3000 rpm, while the motor’s low inertia helps shorten acceleration and deceleration times. Its size 2 frame and B length code reduce overall mass while providing sufficient magnetic stack depth for the intended output.
All electrical terminations are routed through a set of M17 quick-lock SPEEDCON connectors. Power and feedback conductors use a double-cable arrangement with metal braiding for electromagnetic shielding, helping protect feedback signals from nearby electrical noise. Because the motor is supplied with no brake, mechanical clamping or drive-held torque must secure the load when power is removed. Maximum acoustic emission is 65 dB(A), allowing the motor to operate near staffed work areas without unusually high motor noise. The encoder electronics use a logic supply of 4.75 to 5.25 V, so a standard 5 V controller can provide power without level shifting. A plain shaft without a sealing ring simplifies coupling alignment, but the shaft opening requires protection from process fluids during installation and operation.
