Lexium SH3 servo motor. This SH3 series of 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 33.4 Nm and achieves a peak torque of 131.9 Nm. Its nominal speed is up to 3600 rpm depending on the supply voltage. This results in a voltage-dependent nominal power of up to 4190 W. The built-in encoder is designed as a multiturn with 128 periods/revolution (128x1024x4096) as SinCos Hiperface. The electrical connection is made via M40 + M23 connectors, angled by 90° and rotatable. The motor flange is 140 mm for fastening. The drive shaft has a diameter of 24 mm. The shaft end is designed with a feather key and corresponds to protection class IP54. The motor housing corresponds to protection class IP65 with fan. There is no holding brake. The servo amplifiers from the Lexium series Lexium 52 & Lexium 62 are recommended for operating the synchronous motor.
