MSK103D-0300-NN-M1-UG2-NNNN

The Bosch Rexroth Indramat MSK103D-0300-NN-M1-UG2-NNNN belongs to the MSK IndraDyn S Synchronous Motors series and represents a precision-engineered IndraDyn S Synchronous Servomotor. With a motor size 103 frame and a fixed motor length D, this standard-design unit satisfies the only available with length D constraint while ensuring compact installation. Natural convection cooling eliminates the need for external fans, reducing maintenance and noise. Its plain shaft design simplifies coupling and alignment in automated machinery.

High-resolution motion control is delivered through the integrated optical encoder technology with a multiturn absolute encoder turn type and a rotatable encoder connector 240° interface. Communication is handled via the Hiperface encoder interface, providing 128 signal periods per revolution for precise position feedback. An electrically-released holding brake adds a safety layer during power-off conditions, offering a holding brake torque of 60 Nm to secure loads instantly. The robust stator winding features an inductivity of 4,870 mH, ensuring smooth current transitions and low torque ripple under dynamic loads.

At standstill and 100 K, the motor delivers a continuous current of 30.8 A and a continuous torque of 53.0 Nm, enabling reliable holding and slow-speed performance. During peak demands, the servomotor can draw up to maximum current of 94.7 A to generate a maximum torque of 138.0 Nm, making it ideal for high-inertia applications requiring rapid acceleration and deceleration.
