Form factor and mounting — 100 mm flange, 4.3 kg
The BEH18LH1533CA6D uses a 100 mm Asian standard flange with four 9 mm mounting holes, matching the common Lexium 18 frame size for direct bolt-on to machine frames or gearboxes. The shaft is 24 mm diameter with a 45 mm parallel key end, rated for maximum radial force 686 N and axial force 196 N, which sets the mechanical load limits for belt or coupling drive applications.
Performance ratings — torque, speed, and power at 380 V three-phase
Rated for 1.5 kW continuous output power at 380 V three-phase, with a nominal speed of 3000 rpm and a maximum mechanical speed of 3000 rpm — suited for constant-torque applications such as conveyors, indexing tables, or spindle drives that require sustained speed accuracy. Continuous stall torque is 4.77 N.m at 380 V, with a peak stall torque of 14.31 N.m — the 3:1 peak-to-continuous ratio supports short-duration overloads for acceleration or transient loads without oversizing the motor frame.
Feedback and encoder — 23-bit optic multi-turn
Equipped with a 23-bit optic multi-turn encoder providing 8,388,608 counts per revolution — this resolution supports high-precision positioning down to sub-arcminute accuracy for applications like pick-and-place or CNC axis control. The encoder is optic type, which offers higher accuracy and lower jitter than magnetic encoders but requires clean, dry operating conditions — the IP67 rating of the motor body protects the encoder housing from washdown and dust ingress.
Thermal and environmental — IP67, air-cooled, no holding brake
IP67 degree of protection means the motor is sealed against dust and temporary immersion — suitable for food-and-beverage washdown zones or outdoor installations where hose-down cleaning is routine. Cooling is air-cooled (natural convection or forced air via the machine's ambient flow) — no liquid cooling circuit required, simplifying installation and maintenance. This variant ships without a holding brake — for vertical-axis or safety-hold applications, an external brake or a motor variant with integrated brake must be specified.
Electrical parameters — torque constant, back EMF, and current ratings
Torque constant is 0.984 N.m/A at 40 °C, and back EMF constant is 65.28 V/krpm at 40 °C — these values define the motor's voltage-to-speed and current-to-torque linearity for drive tuning and sizing the servo amplifier. Continuous stall current is 4.86 A, with a maximum current Irms of 14.58 A at 1.5 kW, 380 V — the drive must be capable of supplying the peak current for acceleration and deceleration phases without entering current limit. The motor has 10 poles, which influences the electrical frequency at rated speed (3000 rpm → 250 Hz electrical) — the drive's switching frequency and current loop bandwidth must accommodate this.
