Product Description:
The MS2N07-D0BNN-CMUH0-NNNNN-NN Synchronous Servo Motor is engineered for high efficiency motion control. It features a smooth shaft without a shaft sealing ring. The motor delivers high power density and precise position feedback with compact dimensions.
The MS2N07-D0BNN-CMUH0-NNNNN-NN servo motor from Bosch Rexroth is self cooling and includes a multiturn absolute encoder. It is built to withstand industrial conditions with black standard varnish coating. At 20°C cold condition, the motor delivers a maximum torque of 79.7 Nm. It has a winding inductance of 10.0 mH that supports smooth torque generation and controlled current rise. The encoder system is multiturn absolute that is capable of recording up to 4,096 revolutions. The rated speed at 100 K is 2940 revolutions per minute. It has a leakage capacitance of 4.0 nF which meets EMC compliance standards. The rated power output of this motor is 5.2 kW at 100 K. The total motor mass is 17.5 kg that offers a balance between compactness and mechanical stability. The rotor is built with 5 pole pairs to enhance synchronous rotation and torque output. It can operate at a maximum electrical speed of 6000 RPM. The surface is treated with a standard black RAL 9005 varnish to provide corrosion resistance and visual uniformity in installations.
The MS2N07-D0BNN-CMUH0-NNNNN-NN servo motor from MS2N series draws 11.55 A at 60 K and delivers a torque of 22.0 Nm. The torque constant is rated at 2.04 Nm/A at 20 °C that ensures effective torque control with optimized current levels. Its thermal time constant is 18.7 minutes. This helps stabilize motor temperature during intermittent or continuous operation. The rotor has a moment of inertia of 0.0021 kg·m² that allows rapid dynamic response and accurate positioning.
