Product Description

The MSK070E-0300-NN-M3-BG0-NNAN is a MSK series motor from Bosch Rexroth. MSK motors are used as rotary main and servo drive motors. The typical fields of application are machine tools, robotics, metal forming machines and printing machines. A drive controller connected to the motor must be programmed prior to startup. Operation of MSK motors is only permitted under assembly, mounting and installation conditions, and under the approved environmental conditions. Torque-speed characteristics for MSK motors are provided for two temperature models: 60K temperature increase on the housing and 100K temperature increase on the motor winding. The 60K data are valid for 40 degrees Celsius ambient temperature and insulated construction. The 100K data are given for 40 degrees Celsius ambient temperature and non-insulated construction. The motor is designed for natural convection cooling.

Technical data for 60K condition include 23 Nm standstill torque and 15.4 Amps standstill current. Technical data for 100K condition include 25 Nm standstill torque and 16.7 Amps standstill current. Maximum torque that the MSK070E-0300-NN-M3-BG0-NNAN motor can deliver is 65 Nm. Maximum current that the motor can deliver is 49.3 Amps. The torque constant at 20 degrees Celsius is 1.64 Nm/A. The voltage constant for the motor at 20 degrees Celsius is 101 Volts/1000 RPM. The resistance of the motor windings at 20 degrees Celsius is 0.53 Ohms. The inductance of the motor windings is 3.9 millihenry. Thermal time constant for the MSK070E-0300-NN-M3-BG0-NNAN motor is 32 minutes. A capacitive multiturn encoder is included with the motor. The power and feedback connectors are 240 degree rotatable. The main shaft on the motor is plain and has a sealing ring. The MSK070E-0300-NN-M3-BG0-NNAN does not include a holding brake.
