Product Description

The SD-B4.180.020-00.000 permanent-field servomotor by Bosch Rexroth uses ferrite material for the permanent magnets in its rotor. This motor delivers maintenance-free operation because of the brushless construction of its tacho. The product is used in combination with an inverter. This device is intended to be used for applications in position and velocity servo loops. The unit is characterized by a constant torque throughout the speed-torque characteristic range. It encompasses a shaft with a keyway as well as a featherkey according to DIN 6885 specifications. This motor portrays a nominal speed rating of 2000 rpm.

The product has a B construction index. This device has an IP 54 protection rating with mated connectors and specified cable diameter. The unit portrays a maximum noise rating of 64 dB (A) at a distance of 1 m. It cannot be mounted vertically in the IM V1 orientation or diagonally. This motor may depict a high surface temperature. The product encompasses a NTC thermostat that is evaluated by the inverter in its winding. This device has a mechanical time constant of 5.8 ms at 20 °C.

The servomotor must have the plastic protective caps fitted firmly on the connectors during transport so that the sockets do not get damaged. This unit allows only its tacho board and mating connectors to be dismantled for replacement. Its type label is located on the housing surface. This motor comprises ball bearings that have a minimum service life of 20,000 operating hours at the flange end. The product must be matched with the inverter in terms of their current ratings. This device is compatible with a TA series inverter with a peak current rating of 17 A / 35 A.
