BSH servo motor from the Lexium 32 servo drive series. This BSH series of three-phase AC servo motors has a low rotor moment of inertia, which enables high acceleration capability for dynamic applications. Thanks to the winding technology, a higher power density is achieved in a compact design. This servo has a nominal continuous stall torque of 2.2 Nm and achieves a peak torque of 7.6 Nm. Its nominal speed is up to 7200 rpm depending on the supply voltage. This results in a voltage-dependent nominal power of up to 1360 W. The built-in encoder is designed as a single-turn with 128 periods/revolution (128x1024) as a SinCos Hiperface. The electrical connection is made via 2x M23 connectors, angled by 90° and rotatable. The motor flange is 70 mm for fastening. The drive shaft has a diameter of 11 mm. The shaft end is designed with a key and complies with protection class IP54. The motor housing complies with protection class IP65. There is no holding brake. The Lexium LXM32 series servo drives are recommended for operating the synchronous motor.
