What the BEH18MM1523MF6D delivers in a motion axis
The BEH18MM1523MF6D is a Lexium 18 servo motor with an integrated holding brake, rated 1.5 kW continuous power at 380 V three-phase. Nominal speed is 2000 rpm, with a peak stall torque of 21.48 N.m and a holding torque of 16.0 N.m — enough to keep a vertical load stationary without a separate brake resistor. The 17-bit magnetic multi-turn encoder gives absolute position feedback over multiple shaft revolutions, so the drive knows the machine position at power-up without a homing cycle. This matters for applications like gantry pick-and-place or rotary indexing tables where lost position after a power cycle means a recovery routine.
Mounting and environmental fit
The motor flange is 130 mm (Asian standard flange), with a 22 mm shaft diameter and an 8.0 mm parallel key. Depth is 174.5 mm, width 183.6 mm, height 130 mm — the envelope fits within a standard servo motor footprint for this power class. IP67 rating means the motor body and connector interface are sealed against dust ingress and temporary water immersion — suitable for washdown environments in food-and-beverage or packaging lines. The two-connector electrical interface (male/female) simplifies cable replacement without opening the motor housing. Maximum radial force Fr is 686 N and maximum axial force Fa is 196 N — stay within these limits for belt-drive or direct-coupling applications to avoid bearing overload.
Sourcing and lifecycle — active production
The motor is part of the Lexium 18 family, which shares a common feedback interface and connector pinout with the Lexium 28 and Lexium 32 drive families — a replacement or second-source assessment should verify the specific drive model compatibility, but the encoder type (17-bit magnetic multi-turn) is standard across the series.
