What the 1 kW rating means for your axis
The BEH18MM1023MF6C is a 1 kW servo motor from the Lexium 18 range, delivering 4.77 N·m nominal torque at 220 V single-phase input. That continuous torque number is what you size the axis against — the peak stall torque of 14.31 N·m is available for acceleration transients but not sustained duty. The 17-bit magnetic multi-turn encoder gives absolute position feedback, so the drive knows the shaft angle at power-up without a homing move. That saves a cycle on every machine start — useful on indexing tables or pick-and-place axes where lost time is lost throughput.
Holding brake and vertical-axis safety
A holding brake is integrated, rated at 16.0 N·m static torque. That brake holds the load when power is removed — critical on vertical axes where a free-falling load is a safety and machine-damage risk. The brake engages when the motor drive is de-energized; it is not a dynamic braking resistor for deceleration. IP67 sealing means the motor body and the connector interface resist dust ingress and water jets. That suits washdown zones in food processing or outdoor conveyor sections where coolant spray is routine. The connector O-ring is the wet-end seal — verify the mating cordset is also rated IP67 to maintain the enclosure.
Mounting and mechanical fit
The motor uses an Asian standard flange with a 130 mm square face and four mounting holes. Shaft diameter is 22.0 mm with a parallel key (8.0 mm key width) and 58.0 mm shaft length. Maximum radial force on the shaft is 686 N; maximum axial force is 196 N. Exceed those and the bearing life drops fast — belt-drive or overhung-load applications need a force calculation before committing the BOM.
