Product Description:
The MS2N07-C1BRN-CMSK1-NNNNN-NN is an MS2N synchronous motor from Rexroth that is designed as a 3-phase permanent magnet unit for automation control. It offers a standstill torque of 14.5 Nm for static operations and it provides rated torque output of 7.05 Nm during continuous operation.
The MS2N07-C1BRN-CMSK1-NNNNN-NN motor includes an advanced ACUROlink feedback system that uses a 20-bit optical multiturn encoder for absolute position to ensure accurate control with functional safety support. Its encoder voltage supply ranges from 7 to 12 volts and its signal interface supports digital communication. This motor generates a maximum torque of 46 Nm at 20°C and its rated power usage is 2.66 kW at 3610 r/min speed. Its maximum speed limit is 6000 r/min and in normal conditions its current requirement is 6.3 A during rated load, while its maximum current capacity is 42.7 A for peak load conditions. The torque constant of the winding is 1.3 Nm/A and its rotor inertia value is 0.00331 kg·m² for dynamic motion profiles. The MS2N07 motor depends on self-cooling method via convection and radiation through the motor surface. It has thermal class 155 insulation for heat resistance and supports B5 flange mounting. The unit features an M23 rotatable single-cable connector and its housing is coated with RAL 9005 black varnish finish.
The MS2N07-C1BRN-CMSK1-NNNNN-NN motor has an integrated electrically released holding brake rated at 24V DC that provides 20 Nm holding torque for static positioning, while its disconnection time is limited to 100 milliseconds and its inertia is measured as 0.000255 kg·m². The protection class of the MS2N07 motor housing is IP65 from dust and water. Its shaft type is half keyway and mechanically balanced, while it is accompanied by a protective sealing ring as well.
