Product Description:
The MSK100D-0300-NN-M3-AP2-NNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a synchronous drive element, it provides closed-loop rotary motion for positioning and speed-regulated industrial axes. This motor is suited for automated equipment that needs repeatable acceleration, stable speed control, and accurate response to changing loads. The unit is built in motor length D with size 100 and follows a standard mechanical design. An electrically released holding brake is integrated so loads remain stationary during power interruptions, and winding code 0300 identifies the electromagnetic package used for this variant.
Thermal management relies on natural convection, so no external fan or liquid loop is required. The brake supplies 70 Nm of static torque to secure vertical or overhung loads. The housing carries an IP65 rating that seals internal components against dust and water jets. Continuous operation is specified between 0 – 40 °C, and the Class 155 insulation system tolerates elevated winding temperatures without premature aging. Power leads terminate on the motor’s A-side, which helps when the connection area must face a control cabinet or cable tray. This cable direction can also simplify routing where the machine frame leaves limited space around the rear of the motor.
Position feedback is generated by a Hiperface interface that transmits both encoder and parameter data to the drive. The sensor delivers 16 signal periods per mechanical revolution, and its multi-turn absolute electronics record up to 4096 shaft revolutions without external batteries. This capacitive measuring principle resists magnetic interference and helps maintain stable feedback where nearby power components may introduce electrical noise. The drive can use this feedback for commutation, speed regulation, and position tracking throughout operation. A keyed output shaft provides positive mechanical locking, and the drive end is a shaft with a keyway so standard couplings can be fitted without custom machining.
