Lexium 18 servo motor with brake — 2.4 kW, IP67, 23-bit encoder
The BEH18MR2413CF6D is a 2.4 kW servo motor from the Lexium 18 range, built for applications that need a holding brake — 50 Nm holding torque keeps the load locked when power is removed. The motor is air-cooled, uses a 10-pole design, and delivers 15.28 Nm nominal torque at 1500 rpm on a 380 V three-phase supply. The 23-bit optic multi-turn encoder provides absolute position feedback over multiple shaft revolutions, which means the drive knows the exact rotor position at power-up without a homing cycle. The IP67 rating on the motor body means it handles washdown environments — food processing, packaging, or any line where hoses are the cleaning tool.
Sizing and mechanical fit — flange, shaft, and forces
The motor uses an Asian standard flange with a 180 mm mounting face and four mounting holes. The shaft is 35 mm diameter with a 79 mm length and a 10 mm parallel key — this is a standard interface for coupling to a load through a belt, gearbox, or direct drive.
Electrical ratings — torque, current, and speed limits
Continuous stall torque is 15.28 Nm at 8.49 A continuous stall current. Peak stall torque reaches 45.84 Nm at 25.48 A maximum current — this is the short-term overload capability for acceleration or overcoming a jam. The torque constant is 1.8 Nm/A at 40 °C, and the back EMF constant is 118.69 V/krpm at the same temperature. Maximum mechanical speed is 3000 rpm, but the nominal operating point is 1500 rpm at 380 V. The motor is wound for 380 V three-phase input; the 2.4 kW continuous power rating applies at that voltage and speed. Electrical connection uses two male/female connectors — one for power, one for feedback.
