Product Description:
The SD-B4.070.030-05.000 Bosch Rexroth permanent-field servomotor features Class F insulation according to DIN VDE 0530 specifications. This motor supports IM B5 and IM V3 mounting orientations. The product is capable of executing electronic commutation. This device is always used along with a TA series or a TC series inverter with a 10 / 20 A peak current rating. The unit comprises a flange of size 142 mm. It encounters axial and radial forces on the shaft during the operation phase. This motor has no temperature related expansion at the driving side because of the fixed bearing.
This product has different maximum limits for the axial force encountered with different mounting orientations. The device does not have any built-in encoder to support its operation. This motor must not be subject to a knocking or hammering of the shaft as this tends to damage the rotor and ball bearings. Its tacho helps in rendering velocity feedback. The product portrays a large overload capacity. This device uses plastic right-angled or straight connectors for the power and feedback connectors.
The servomotor may have a high surface temperature during the operation. This unit must be allowed to cool down before touching it if a touch guard cannot be used for this purpose. It depicts a torque constant of 0.93 Nm/A. The product must at all times be free of fluid retention on the flange end plate with vertical installation. The unit should be used in the original state without any structural modification except for the tacho board replacement.
