Product Description

Bosch Rexroth’s MSK synchronous motors set new standards as they are manufactured using the latest technologies. They have a compact construction and are characterized by high dynamics and high torque density. The motors have also been equipped with innovative optical encoder systems, accounting for their high precision. The MSK motors are used as rotary main and servo drive motors and have a wide range of applications. They are used in machine tools, printing and paper processing machines, food and packaging machines, metal forming machines, and robotics.

The MSK071C-0200-NN-M2-UG0-RNNN has four pole pairs and a maximum speed of 3,500 revolutions per minute. Its encoder system is the multiturn absolute optical encoder with a system accuracy of ±20 angular seconds. The encoder permits absolute, indirect position detection and preserves the information obtained even after the machine is switched off. This motor’s temperature is monitored by two independent systems: the temperature sensor and the temperature model. These systems protect it against irreversible damage from thermal overload. The temperature sensor is built into the stator of the motor, and its connection is built into its power connector.

The standard design of the MSK071C-0200-NN-M2-UG0-RNNN makes it a self-cooling motor with heat dissipation realized over natural convection to the ambient air and by heat conduction onto the machine construction. It has an average weight of 13.9 kg and should be set up at a maximum height of 1000m above mean sea level. It should also be operated at a maximum temperature of 40°C and relative humidity of 95%. The motor is equipped with a plain shaft which provides a non-positive, zero-backlash shaft-hub connection with a high degree of quiet running.
