MS2M02-B0FNN-KMDL0
MS2M Ultra Compact Motors
The MS2M02-B0FNN-KMDL0 is an ultra-compact servo motor developed by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. It is a frame size 2 motor with frame length B, designed to deliver precise rotary motion to positioning tables, pick-and-place heads, and other automation axes where space is limited. This layout suits compact machinery that needs accurate motion without using a larger motor envelope. A keyed shaft without a sealing ring transmits torque directly, and the motor is supplied without a holding brake, so applications must rely on external clamping or drive torque for power-off retention.
The stator winding is rated for a nominal speed of 3000 rpm, and the rotor has 5 pole pairs, which sets the electrical frequency required for synchronous operation. The housing is rated IP65, which helps prevent dust ingress and withstands water jets during washdown cleaning. The integrated encoder electronics accept a regulated supply of 4.75 to 5.25 V, and thermal management relies on natural convection, so no fan is required. Because cooling is passive, the motor can be installed where added airflow hardware would be difficult to place. The motor is intended for continuous duty in ambient temperatures from 0 to 40 °C.
High-resolution feedback is provided by an on-shaft 23-bit optical encoder, available in single-turn or multi-turn formats for accurate position feedback. Power and signal leads terminate through M17 quick-lock SPEEDCON connectors, which allow fast connection without threaded couplers. A lightweight rotor with low motor inertia supports rapid acceleration and deceleration while helping limit thermal rise during dynamic motion. The encoder also allows the drive to maintain stable commutation and precise positioning during repeated motion cycles. Acoustic output remains limited to 65 dB(A).
