Product Description

Designed to meet a wide range of factory automation needs, the MSK servo motors by Bosch Rexroth feature a compact build, precise encoder systems, and high torque density. They are commonly used in general automation applications but can be upgraded to meet other application-specific requirements.

The MSK100B-0300-NN-M1-RP2-NNNN is one of the self-cooling synchronous servo motors in the MSK series by Bosch Rexroth. Its cooling mechanism is natural convection, where the heat generated during the motor’s operation is eliminated via heat transfer to the ambient air. Some of this heat is also transferred to the walls of the machine construction by conduction. A thermal sensor of the KTY84 type protects it from permanent damage due to thermal overload. It does this by alerting users at a threshold temperature of 140 °C and initiating shutdown at 150 °C. This motor’s nominal speed is 3,000 revolutions per minute, and its maximum speed is 4,500 revolutions per minute.

Maintenance-free operation is possible in the MSK100B-0300-NN-M1-RP2-NNNN, provided that it is operated within specified conditions. It is equipped with a multiturn encoder that records its absolute, indirect position recording within 4,096 mechanical motor rotations. The encoder uses the optical measuring principle and preserves the absolute position of the motor’s axis even after a switch-off. Its data memory stores vital information about the motor and enhances its rapid boot-up and its risk-free adjustment to its drive controller. This MSK model is coated in a varnish that consists of a black (RAL9005) 2K epoxy resin coating based on epoxy polyamide resin in water. The coat is highly resistant to dilute acids and alkaline solutions, current mineral oils, sewage, and water.
