Frame size and mounting — what the 176 mm depth means for your panel
The BEH18LH1533MF6D measures 176 mm deep by 100 mm wide by 144.5 mm high, with a 100 mm Asian standard flange and 9 mm mounting holes. That frame size fits the Lexium 18 footprint — plan for the motor body plus the connector overhang when laying out the machine baseplate.
Torque and speed — matching the load to the motor's capability
Rated 1.5 kW continuous output at 380 V three-phase, the motor delivers 4.77 N.m nominal torque at 3000 rpm. The continuous stall torque matches the nominal at 4.77 N.m — the thermal limit is the same whether turning or stalled, so the duty cycle determines how long you can hold torque at zero speed. Peak stall torque reaches 14.31 N.m — roughly 3× the continuous rating — for acceleration and short-duration overloads. The torque constant of 0.984 N.m/A at 40 °C means the drive current scales linearly with demanded torque; the maximum current of 14.58 A at 1.5 kW sets the drive's peak output requirement. The 10-pole rotor design gives a relatively low cogging torque profile, which helps smooth low-speed tracking. Maximum mechanical speed is 3000 rpm — the back EMF constant of 65.28 V/krpm at 40 °C means the drive's DC bus voltage must stay above the generated voltage at top speed to maintain current control.
Encoder feedback — 17-bit magnetic multi-turn for absolute position retention
The magnetic multi-turn encoder provides 17 bits of resolution per revolution, giving 131,072 counts per turn. Multi-turn tracking retains the absolute position over 4096 revolutions — no homing sequence needed after a power cycle if the shaft hasn't been turned past that range. Magnetic encoders are more tolerant of contamination than optical types — the IP67 rating on the motor body means the encoder cavity stays sealed against washdown and dust ingress. The two-connector electrical interface (male/female) carries power, feedback, and the brake wires in a single plug-and-play cable set.
Holding brake — 8 N.m for vertical-axis safety
The integrated holding brake delivers 8 N.m of holding torque — sufficient to hold the rated load on a vertical axis when power is removed. The brake is spring-applied, power-released: it engages on power loss or E-stop, so the load stays put without relying on the drive's holding current.
Bearing loads and cooling — radial and axial force limits for direct coupling
The motor bearings are rated for a maximum radial force of 686 N and a maximum axial force of 196 N. These limits govern belt-drive or overhung-load applications — a direct coupling with a flexible element usually stays well within both, but a belt tensioning force that exceeds the radial limit will shorten bearing life. Cooling is air-cooled (self-ventilated), not separately fan-forced. The continuous torque rating assumes free airflow around the motor body; mounting in a confined pocket or with thermal blankets will require derating.
