This product is part of the Lexium 32 range, an offer of servo drives from 0.15kW to 11kW and associated servo motors. This servo motor has a maximum mechanical speed of 3500RPM, a continuous stall torque of 65Nm, a keyed shaft end, and a holding brake. It is equipped with a Multi-turn SinCos Hiperface® feedback with 131072points/turn x 4096turns speed feedback resolution. It is a servo motor with a rated supply voltage of 480V, a continuous stall current of 36.1A and a continuous power of 7.95W. The shaft dimensions are 38mm (diameter) x 80mm (length). It is furnished 2x rotatable right-angled connectors for power and encoder connections. It is an IP65 standard rated product (shaft and housing). It measures 310mm long without holding break, 368mm long with holding break, 262mm high, and its flange size is 190mm. It weighs 44.5kg. BMH servo motors associated with the Lexium 32 servo drive are intended for applications such as Packaging, Textile, gantry cranes, Hoists. Lexium BMH servo motors conform to international standards IEC/EN 61800-5-1, IEC/EN 61800-3, are UL and CSA certified, and CE marked. This motor is designed to be compatible with Lexium 32 servo drive, encoder and power cables, optional IP67 conformity kit, gearbox option and braking resistor. It installs on 4x holes (14mm diameter), the circle diameter of the mounting holes is 215mm. Lexium 32 is a servo drive range providing drive and motor combination that has exactly the right power, performance and functionality. The Lexium 32 range includes four servo drive models with power ratings from 0.15kW to 11kW, and two servo motor ranges, BMH and BSH series.
