Product Description:
The synchronous motor MS2N07-C0BQN-CSSH1-NNNNN-NN from Bosch Rexroth is designed with a smooth seal less shaft that measures 32 mm in diameter and 58 mm in length. It possesses a standard flange exactness of 140 mm and it comes equipped with standard ball bearing that can attain a maximum operating speed of 6000 r/min.
The MS2N07-C0BQN-CSSH1-NNNNN-NN motor uses self-cooling mechanism of IC410 standard to manage heat under standard ambient conditions. It includes an electrical release design of holding brake that operates on a 24 V DC supply and it provides 20 Nm of holding torque along with 12.2 Nm of dynamic torque. The brake system takes 100 ms of disengaging time and 40 ms of connection time. The motor has a total weight of 14.0 kg including the brake and its rotor moment of inertia is 0.00146 kg·m². It uses a single-cable electrical connection with an M23 connector and utilizes 7.5 A of rated current at 100K along with 3.84 kW of power from a 400 VAC supply source. This MS2N motor has a built-in single-turn encoder that operates with 20 bits of resolution and provides precise position feedback with accuracy of 36”. The encoder functions on a DC source of 7 to 12 V and uses 60 mA of current.
The MS2N07-C0BQN-CSSH1-NNNNN-NN motor features a winding impedance of 0.776 Ohms and its inductive value is specified at 10.5 mH. It offers IP65 protection degree and uses insulation class F in its construction for thermal safety. This MS2N07 motor performs at a steady speed of 4070 r/min and delivers 9.0 Nm of rated torque while its standstill torques is 16.0 Nm at 100 K. It generates a constant torque of 1.37 Nm/A and possess a measured back emf of value 83.1 V/1000 rotations.
