Power, torque, and speed — the load-matching specs
The BEH18LH1033CF6D: Rated 1 kW continuous output power at 380 V three-phase, with a nominal speed of 3000 rpm and a maximum mechanical speed of 3000 rpm — the motor is sized for constant-torque applications up to that speed ceiling. Nominal torque is 3.18 N.m at 380 V, with a continuous stall torque of 3.18 N.m and a peak stall torque of 9.54 N.m — the peak figure handles acceleration transients, while the continuous rating governs the thermal duty cycle. The holding brake delivers 8 N.m static holding torque, which secures the load on a vertical axis when power is removed — a critical spec for Z-axis or gravity-loaded applications.
Encoder and feedback — 23-bit multi-turn resolution
The optic multi-turn encoder provides 23-bit resolution, giving 8388608 positions per revolution and absolute position tracking over multiple turns — no homing cycle needed after a power cycle. This feedback class suits applications requiring tight position repeatability, such as indexing tables or pick-and-place axes, where the encoder resolution directly sets the minimum move increment.
Environmental and mechanical fit
IP67 rating means the motor body and the connector interface are sealed against dust ingress and temporary immersion — suitable for washdown environments in food processing or packaging lines. The Asian standard flange measures 100 mm square with 9 mm mounting holes, and the shaft is 24 mm diameter with a parallel key — this matches the common Asian servo-mount pattern used on many machine builders' frames. Maximum radial force at the shaft is 686 N and maximum axial force is 196 N — these limits define the allowable belt tension or direct-coupling load without overloading the bearings.
Electrical constants and current draw
Torque constant is 0.924 N.m/A at 40 °C, and the back EMF constant is 63.29 V/krpm at 40 °C — these are the key tuning parameters for the drive's current loop and velocity loop gains. Continuous stall current is 3.44 A, and the maximum current Irms is 10.32 A at 1 kW, 380 V — the drive must be sized to supply at least the peak current for acceleration events.
