Brake holds the load when power drops
The BEH18MM1523CF6D: The integrated holding brake delivers 16.0 N.m of holding torque — enough to keep a vertical axis from drifting when the drive is disabled or power is lost. This isn't a dynamic braking resistor; it's a spring-set, power-off engaged brake that holds the rotor stationary. The brake is rated for static holding only, not for stopping the motor from speed. On a ballscrew or belt-drive, that 16 N.m at the motor shaft translates to a much higher force at the load, so check the mechanical advantage before calling it sized. The motor's peak stall torque is 21.48 N.m at 380 V three-phase, which tells you the electromagnetic torque ceiling before the drive current limit kicks in. The continuous stall torque is 7.16 N.m at the same voltage — the difference is the thermal limit. That 21.48 N.m peak is available for acceleration and deceleration transients, but the drive's current loop and the motor's I²t model will fold it back if sustained too long.
23-bit encoder — position feedback without a second device
The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution and tracks absolute position over multiple turns without a battery-backed counter. That means the controller knows the shaft angle at power-up — no homing sequence needed on a machine that doesn't lose position between cycles. The multi-turn range is 4096 revolutions, which covers most single-stage gearboxes and ballscrew strokes. If your application needs more than 4096 turns of absolute range, you'll need a different feedback option or a secondary reference. Optic encoders are more sensitive to contamination than magnetic types. The IP67 rating on the motor body and connector seals keeps washdown and coolant out, but the encoder itself is inside the motor housing — if the shaft seal fails and cutting fluid works its way in, the optic disc is the first thing to fog. On a machine that sees continuous coolant spray, budget for seal inspection at the motor's service interval.
1.5 kW at 2000 rpm — sizing the drive match
Nominal output power is 1500 W at 380 V three-phase, with a nominal speed of 2000 rpm and a nominal torque of 7.16 N.m. The continuous stall current is 4.27 A, and the maximum permanent current (the drive's current limit for the motor) is 12.8 A. That 3:1 current ratio between continuous and peak is typical for a servo — the motor can deliver short bursts of high torque for acceleration, but the RMS current over the duty cycle must stay at or below 4.27 A to avoid overheating. If your move profile has a high duty cycle, the drive's I²t model will limit the peak current, and you'll see the torque drop off in the middle of the cycle. The maximum mechanical speed is 3000 rpm, which is 50% above the nominal speed. Running above 2000 rpm means the torque drops off because the back EMF (110.2 V/krpm at 40 °C) approaches the bus voltage. If you need the full 1.5 kW at 3000 rpm, you'll need a drive with a higher DC bus voltage or a motor with a lower back EMF constant. For most applications, the nominal 2000 rpm point is where the motor is thermally and electrically balanced.
IP67 and the Asian standard flange — mounting constraints
IP67 means the motor body is dust-tight and protected against temporary immersion in water up to 1 meter for 30 minutes. The electrical connection uses 2 connectors, male/female, which are sealed at the mating face. For washdown environments, make sure the mating connector's IP rating matches — an unsealed cable gland on the drive side breaks the protection chain. The motor is air-cooled, so it relies on surface convection; mounting it in a tight enclosure with no airflow will derate the continuous torque.
Active production — no obsolescence worry
Lifecycle stage is marked as current, meaning Schneider Electric still manufactures this motor as an active catalog item. No end-of-life notice, no last-time-buy deadline. For a BOM freeze, this is the cleanest position — you can order production quantities through authorized distribution without worrying about a forced redesign.
