MSK103B-0300-NN-S1-UG0-NNNN

Product Description

The MSK103B-0300-NN-S1-UG0-NNNN is a servo motor with maximum speed of 4700 RPM. The motor weight is 22.5 kilograms. The motor is designed by Bosch Rexroth and is part of the MSK family of synchronous motors. The motor enclosure is painted matte black and has an environmental protection rating of IP65. This rating allows motor installation outside control cabinets and near the operating machinery. Hence the cost of installation is reduced and maintenance cost is also reduced. The MSK103B-0300-NN-S1-UG0-NNNN requires 0 to 40 degrees Celsius ambient temperature for optimal performance. Operating the motor outside this temperature range will cause the internal temperature of the motor to go above safe levels. This will adversely affect motor operation and can also cause the components to fail. The sound pressure produced by an operating MSK103B-0300-NN-S1-UG0-NNNN always stays below 75 dB.

The thermal class of the MSK103B-0300-NN-S1-UG0-NNNN motor is 155. The thermal time constant is 27 minutes. The winding inductance is 8 millihenry. The winding resistance is 0.36 Ohms when measured at 20 degrees Celsius. The voltage constant is 108 Volts/1000 RPM when measured at 20 degrees Celsius. The torque constant is 1.76 Nm/Amps when measured at 20 degrees Celsius. The rated torque is 28 Nm and the maximum torque is 85 Nm. The rated current is 17 Amps and the maximum current is 63 Amps. The MSK103B-0300-NN-S1-UG0-NNNN cools via natural convection. The feedback device on the MSK103B-0300-NN-S1-UG0-NNNN motor is a singleturn optical encoder with 128 signal periods. The motor shaft is plain and includes a sealing ring that protects motor bearings from dust and moisture.  The MSK103B-0300-NN-S1-UG0-NNNN motor does not feature a holding brake. The power and feedback connectors are 240-degree rotatable.
