Rated performance — what the numbers mean at the spindle
The BEH18MM1313CF6D: On a 380 V three-phase supply, this motor delivers 1300 W continuous power at 1500 rpm nominal speed, with 8.34 N.m nominal torque — that's the torque you can hold indefinitely without overheating, and it's the figure to size your load against for continuous-duty applications like conveyors or spindle drives. Peak stall torque hits 25.02 N.m at 380 V — that's the short-term punch for acceleration or overcoming static friction, but the drive's current limit must be set to respect the 14.91 A maximum permanent current to avoid demagnetizing the rotor. The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution — that resolution means the drive sees position down to sub-arcminute level, which matters for synchronized axes or cam profiles where cumulative error kills cycle time.
Brake and feedback — what's built in
The holding brake delivers 16.0 N.m holding torque — enough to hold a vertical load at standstill without the drive holding current, so the motor doesn't droop when power is removed. The brake is spring-applied, power-released; it engages on power loss as a safety feature. Feedback comes from a 23-bit optic multi-turn encoder — this gives absolute position across multiple shaft revolutions, so the controller knows the axis position immediately on power-up without a homing cycle. The optic sensor is more accurate than magnetic at low speed but needs clean air — IP67 keeps washdown and dust out of the encoder housing.
Environmental sealing and cooling
IP67 means the motor body and connector are sealed against dust ingress and temporary immersion — it survives washdown on food-processing lines or wet environments, but the shaft seal isn't rated for continuous submersion or high-pressure spray (IP69K). Air-cooled via the motor's own fan — no external blower or water circuit needed, but the fan noise and airflow path should be clear of obstructions in the cabinet.
