Product Description

The Bosch MSK100C-0300-NN-M2-AP2-RNNN is a digital servo motor. It includes a 70 Nm rated holding brake. The combined weight of the motor and the brake is 48.9 kilograms. The brake operates according to the electrical release principle and allows shaft rotation after application of a 24 Volts DC signal. Protection class of the motor is IP65. The thermal class for the MSK100C-0300-NN-M2-AP2-RNNN motor is 155 according to EN 60034-1. The motor is a flange mounted device. The size of the motor flange is 165 millimeters. Length of the MSK100C-0300-NN-M2-AP2-RNNN motor is approximately 359 millimeters. Centering diameter of the motor is 180 millimeters. The shaft on the motor includes a keyway and a shaft seal. The shaft seal prevents oil leakage and protects motor bearings. The shaft diameter is 38 millimeters.

The MSK100C-0300-NN-M2-AP2-RNNN motor gets electrical power from a servo controller. The power socket is on side A of the motor housing. Customers can select one of four positions for the power socket. The motor encoder is a multiturn encoder. The encoder is rated for 2048 signal periods. Singleturn encoders are also available for MSK motors. Bosch provides MSK motors with multiple housing designs. The housing of the MSK100C-0300-NN-M2-AP2-RNNN motor features increased concentricity and run-out. The motor supports two cooling methods: natural convection and surface cooling. Continuous torque and current output of the MSK100C-0300-NN-M2-AP2-RNNN motor are higher with surface cooling. Therefore customers with higher load requirements can operate the motor with surface cooling. The thermal time constant of the motor is 90 minutes. The maximum speed of the motor is 4500 RPM. During operation the MSK100C-0300-NN-M2-AP2-RNNN produces a sound pressure level that does not exceed 75 dB.
