Sizing the BEH18LH1033CA6C for the load
Continuous power is 1000 W at 220 V single-phase input, with a nominal torque of 3.18 N.m at 3000 rpm. That torque constant of 0.51 N.m/A at 40 °C means each amp of drive current delivers just over half a newton-meter — useful for estimating the drive's continuous current requirement from the load torque. Peak stall torque hits 9.54 N.m at 220 V, drawing 18.75 A — roughly three times the continuous stall current of 6.25 A. That headroom handles acceleration and emergency stops without tripping the drive, but the cabling and drive I²t rating need to support that peak. Back EMF constant is 34 V/krpm at 40 °C. At 3000 rpm the motor generates 102 V back EMF, leaving about 118 V of bus headroom for the drive to push current against — comfortable for a 220 V bus, but worth checking if the application runs near the voltage ceiling.
Encoder feedback and positioning resolution
The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution. On a 5 mm pitch ballscrew that works out to roughly 0.0006 mm per count — holds the micron in a tuned loop, no jitter. No holding brake on this variant — the shaft freewheels when power is removed. For vertical axes or any load that must hold position at standstill, budget for an external brake or a drive with a holding brake output.
Mounting and environmental fit
Asian standard flange with a 100 mm square pilot, four 9 mm mounting holes on a 115 mm bolt circle. Shaft is 24 mm diameter with a parallel key, 45 mm long — mates with standard metric couplings and pulleys. IP67 rating means the motor body and shaft seal withstand washdown — suitable for food-and-bev lines or coolant spray on a machining center. Air-cooled, so keep the ambient airflow clear of obstructions.
