7.5 kW continuous at 1500 rpm — the rating that sets the BOM line
The BEH18MR7513CA6D is a Lexium 18-series brushless AC servo motor from the BEH18 family, sized at 7500 W continuous output power with a nominal torque of 48 N.m at 1500 rpm on a 380 V three-phase supply — meaning it is the high-power end of the BEH18 line and pairs with a similarly rated Lexium 18 servo drive to deliver positioning or speed-controlled duty. Peak stall torque reaches 120 N.m at 380 V three-phase against a continuous stall of 48 N.m, so the motor can deliver roughly 2.5× nominal torque for short acceleration or jam-stop events without leaving its thermal envelope — a useful headroom figure when sizing the drive's peak current limit.
23-bit multi-turn feedback and what that means in the loop
An optic encoder delivers 23 bits of multi-turn position feedback — a resolution on the order of 8.4 million counts per turn plus multi-turn gear tracking — which is more than adequate for high-precision positioning and gives the drive the data density it needs to close a tight current and velocity loop. Maximum mechanical speed is 3000 rpm with a torque constant of 1.815 N.m/A at 40 °C and a back-EMF constant of 127.67 V/krpm at 40 °C — the drive must be configured to handle the bus voltage rise at top speed, and the constant relationship lets you read expected current directly from commanded torque.
Mechanical envelope, shaft, and shaft load ratings
The shaft is 42.0 mm diameter with a 12.0 mm parallel key over a 113.0 mm length, supplied without a holding brake and without a second shaft end — so any brake must be sourced on the driven load side if the application requires a failsafe stop, and the single shaft end means the coupling has to take any axial misalignment rather than a flexible second coupling. Shaft load limits are 588 N maximum axial force and 1764 N maximum radial force — these are the numbers to check against the driven machine's overhung load and thrust, because exceeding either will wear the bearings long before the motor's electrical ratings trip a fault.
IP67 sealing and air cooling — where it can be deployed
IP67 on the motor housing means the BEH18MR7513CA6D resists dust and temporary immersion, so it can sit on machines where the cabinet is open or where washdown is routine — a fit for food-and-bev lines, outdoor skids, and damp process areas where a standard IP65 servo would be marginal.
Lifecycle posture and how to source it
Electrical connection is via two male/female connectors, stator resistance is 0.134 Ohm, and the motor carries 10 poles across three phases with a continuous stall current of 26.45 A and maximum Irms of 60.23 A at 7.5 kW — the connectors are the only thing standing between a swap-out and a re-pin, so identify the mating connector family before committing the replacement.
