Product Description

The SD-B5.380.020-04.000 is an efficient permanent-field servomotor manufactured by Bosch Rexroth. The motor forms an integral component of the manufacturer’s Servodyn drive concept. The device should be operated with a compatible inverter. The product is specifically designed for use in industrial environments. The motor has ball bearings at its driving end where the flange is located. The minimum service life of the ball bearings is 20,000 hours. When installing the device, care should be taken to ensure that there is adequate heat dissipation.

The SD motor is likely to have high surface temperatures. So, if necessary, a touch guard should be provided to avoid burns upon touching the hot surface. The commutation of the phase currents in the inverter is controlled by the motor’s commutation sensor. The motor must not be dismantled by the user. However, the user is allowed to dismantle the tacho board. Before the initial operation of the device, the user must check the motor-module combination with the help of the information provided in the type label. If the motor is connected to a module that is not approved, the operation of the motor will be restricted. It may also cause damage to the device.

The SD motor features an in-built disk brake, which is not a working brake. The brake can be operated only with the axis stationary. The device supports maintenance-free operation by the use of a tacho and motor of brushless construction. The unit’s NTC thermistor is positioned in its windings. The NTC thermistor protects the motor against thermal overload. The product supports straight and right-angled connectors. Temperature-related expansion does not occur at the driving end of the motor due to the fixed bearing at that end.
