BMH servo motor from the Lexium 32 servo drive series. The BMH series of three-phase AC servo motors has a medium rotor moment of inertia and is perfectly suited for applications with high loads. Thanks to the winding technology, a very high power density is achieved in a compact design. This servo has a nominal continuous stall torque of 65 Nm and reaches a peak torque of 195 Nm. Its nominal speed is up to 2000 rpm depending on the supply voltage. This results in a voltage-dependent nominal power of up to 7.75 kW. The built-in encoder is designed as a multiturn with 128 periods/revolution (128x1024x4096) as SinCos Hiperface. The electrical connection is made via M40 and M23 connectors, angled by 90° and rotatable. The motor flange is 190 mm for fastening. The drive shaft has a diameter of 38 mm. The shaft end is designed as a key and complies with protection class IP65. The motor housing complies with protection class IP65. There is no holding brake. The servo amplifiers from the Lexium LXM32 series are recommended for operating the synchronous motor. Thanks to the Green Premium eco-label, you can obtain detailed information on material content, environmental impact and circular economy that supports your sustainability goals.
