Product Description:

The MSK100A-0300-NN-M2-BG0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact electromechanical actuator, it converts drive current into precise rotary motion for positioning tasks in automated machinery. It is suited for servo axes in handling systems, assembly stations, and packaging equipment where accurate speed and position control are required in limited space. Its synchronous design supports smooth rotation and repeatable motion when paired with a compatible servo drive. Delivered without a holding brake, it is intended for installations where mechanical restraint or drive torque maintains standstill position.

Cooling is handled by passive natural convection, so airflow around the housing must remove heat losses without auxiliary fans. Position feedback is supplied through an EnDat2.1 optical encoder, and its digital protocol transmits absolute position, temperature, and diagnostics to the drive over a single shielded pair. Because the feedback channel is digital, the controller can monitor rotor position and motor condition without separate analog tracks. The sensing disk provides 2048 signal periods, which gives fine feedback resolution after internal interpolation. A plain shaft simplifies mounting because no keyway machining is required, which helps reduce coupling runout in compliant connections. The aluminum housing and radial connector gaskets are sealed to IP65, helping block dust ingress and directed water jets.

Continuous operation is specified for ambient temperatures between 0 to 40 °C; outside this window, output torque must be derated or external cooling must be added. The stator insulation has a thermal class of 155, so the winding can withstand elevated operating temperature without premature varnish damage. Dynamic behavior is influenced by the 100 mm frame size and winding code 0300, which correspond to the motor geometry and electrical values used by IndraDrive controllers. These motor values let the controller calculate current response and thermal behavior more accurately during speed changes and load variation.
