Product Description:
The Bosch Rexroth SD-B4.070.030-10.000 permanent-field servomotor has no cylindrical shaft extension as there is no keyway or featherkey. This motor has no disk brake, encoder or second shaft end. The product portrays vibration quality level N according to DIN ISO 2373 specifications. This device incorporates plastic connectors with aluminum securing rings for its connection. The unit portrays advantageous heat dissipation as its total power loss is generated in the stator winding. It is characterized by good synchronization. This motor is an ideal option for mechanical engineering related applications with stringent requirements.
The product has no support for IM V1 mounting with the shaft facing downwards. This device comes with a type label attached to its housing. The unit has an IP protection standard as per DIN 40 050 / 40 053 specifications with the prescribed cable diameter and mating connector. Its stator winding features a low thermal resistance with respect to the motor surface. This motor has a cylindrical shaft end. The product must be handled without any impact on the shaft to avoid the possibility of its rotor and ball bearings getting damaged.
This device must be disconnected from the power supply before any installation or connection work is done on it. The unit can be braked by shorting its windings through braking resistors in an emergency-stop situation. It is compatible with three types of short circuit braking contactors. This servomotor related tacho cable is not suitable for trailing cable operation. The product has a mass of 23 kg.
