Product Description

Designed and made by Bosch, the SF-B5.0250.020-00.000 servo motor belongs to the SF-series. The motor has a smooth shaft and follows the IM B5 type of construction. Except for the output flange, the entire motor is built in accordance with protection type 67. The motor has a plug-in connector for the encoder, brake, and output. The rated speed of the motor is given as 2000 min-1. Furthermore, as far as the dimensions of the motor are concerned, the shaft is 32x58 mm, while the flange is measured to be 190 mm. Interestingly, the maximum length of the motor, without including the length of the holding brake, is 300 mm.

The Bosch SF-B5.0250.020-00.000 servomotor, like many of its counterparts, is a permanently excited synchronous motor that is typically used in conjunction with fully the digital Servodyn-D inverter system. The SR motors that are similar to these SF motors differ only in the fact that they use a resolver instead of an absolute value encoder system. The motor comes with the option of adding a holding brake as well.

SF in the part name highlights the fact that the brushless servomotor comes with an absolute value encoder that can either be a single-turn or multi-turn motor. You should also know that these brushless servomotors are equipped with sinusoidal e.m.f. The letter ‘B’ in the part name corresponds with the design suffix for the motor, while the number ‘5’ denotes the size of the frame of the motor. The motor has a locked-rotor torque of 23 Nm and a nominal motor speed of 4000 min-1. The motor comes with the option for a shaft with a keyway and feather key. It is not supplied with a mating connector or holding brake.
