Product Description:
The Bosch Rexroth SD-B5.250.015-14.000 is a reliable permanent-field servomotor that is designed for use in industrial environments. The device has a torque of 25 Nm. The speed of the motor is 1500 rpm. The unit should always be operated with a compatible inverter supplied by the manufacturer. The product can be mounted vertically or horizontally. However, it can be installed vertically only in the IM V3 position. There isn’t any in-built encoder in the product. The maximum permissible operating temperature of the unit is 40°C. The commutation sensor of the device controls the commutation of phase currents in the inverter connected.
The peak current of the motor at 20°C is 38.7 A. The torque constant is 1.94 Nm/A. The flange of the device is 116 mm long. The unit weighs 58.6 kg. Drive elements, including belt pulleys, gear wheels, and clutch disks, may be fitted and removed only using a suitable extraction and mounting device. The product must not be dismantled. However, its tacho board can be dismantled, if required. The motor features a large overload capacity via heat dissipation. Total power loss is generated in the stator winding. The device has a type label for identification. It also carries the technical details of the motor.
The SD motor portrays good synchronization via a special magnet configuration and accurate current regulation in all 3 phases. There are sockets for tacho, power, and brake connections. The motor connectors have plastic protective caps. These should be screwed on if the device is returned to avoid damage to the sockets during transit. The NTC thermistor in the windings of the motor protects it against thermal overload.
