Product Description

The Bosch Rexroth SD-B5 250.020-10.000 is a reliable permanent-field servomotor in the SD series. The motor has a type label for identification attached to its housing. The device has a fixed bearing present at its driving end. There are three terminals on the servo module that are used to connect to the device. The product is compatible with the TA and TC series of inverters supplied by the same manufacturer. The sockets of the unit can be protected against damage by transportation by keeping the protective caps on the connectors intact at the time of transit. The motor’s electrical connection needs a power plug and a tacho plug.

The SD motor supports both vertical and horizontal mounting orientations. The device is designed for use in position and velocity loops. There is a commutation sensor integrated into the unit. The nominal speed of the motor is 2000 per minute. It has a current of 17.2 A in standstill mode. The peak current of the device at 20 °C is 51.6 A. The motor’s torque constant is 1.46 Nm/A. The length of the product is 489 mm. It has a thermal time constant of 260 minutes. The mass of the unit is 58.6 kg.

The temperature monitoring of the motor is evaluated in the inverter. The device does not come with its mating connectors. They should be ordered separately. The commutation sensor tends to control the commutation of the phase currents within the connected motor. A minimum of one supply module is required for the motor to function. The connection between the motor and the inverter is done through plug-in connectors. The NTC thermistor in the windings of the unit protects it against thermal overload.
