Product Description

The MSK070C-0150-NN-M1-UG1-NSNN is a Bosch Rexroth servo motor. It features a standard and extended design according to group II categories 3G and 3D according to EN 60079 ff. MSK motors are asynchronous motors whose speed is not synchronized to the input current frequency. The power to the MSK070C-0150-NN-M1-UG1-NSNN is supplied by a drive controller. In addition to the power cable that connects the motor to the drive, a feedback cable also connects the two devices. The feedback cable is used by the motor encoder to share feedback with the drive controller. The connectors for the power and feedback connections on the motor are 240-degree rotatable. The MSK070C-0150-NN-M1-UG1-NSNN features an integrated optical encoder rated for 128 signal periods. The main shaft on the MSK070C-0150-NN-M1-UG1-NSNN is smooth and includes a sealing ring.

The MSK070C-0150-NN-M1-UG1-NSNN also includes a 23 Nm electrically releasing holding brake. The motor cools through convection cooling and performs optimally at 0 to 40 degrees Celsius ambient temperature. The number of pole pairs on the MSK070C-0150-NN-M1-UG1-NSNN are six. The moment of rotor inertia is 0.00291 kg m². Thermal time constant of the motor is 22 minutes. The peak motor speed is 2500 RPM. The sound produced by an operating MSK070C-0150-NN-M1-UG1-NSNN motor does not exceed 75 dB. The motor mass including the holding brake is 13.2 kilograms. The motor housing is IP65 rated. Detailed torque-speed curves are provided in the product documentation. Bosch recommends motor transport only inside its original packaging. For motor storage the recommendations from Bosch include storage in original packaging, use of a dust free and dry location and protection from vibrations. The motor should also be protected from light and against direct insolation during storage.
