Lexium 18 servo motor — 2.4 kW continuous, IP67 sealed
The BEH18MR2413CA6C is a 2.4 kW servo motor from the Lexium 18 range, rated for 1500 rpm nominal speed and 15.28 Nm continuous stall torque at 220 V. The 23-bit optic multi-turn encoder delivers 8388608 points/turn feedback resolution, giving the drive precise position and velocity data for tight motion coordination.
Torque, inertia, and load matching
Nominal torque of 15.28 Nm at 220 V with a torque constant of 0.979 Nm/A at 40 °C means the drive current loop scales directly: for every amp of motor current, the shaft delivers just under 1 Nm. Peak stall torque reaches 45.84 Nm for acceleration and overload events, demanding up to 46.7 A from the drive at 2.4 kW. Maximum radial force Fr is 1470 N and maximum axial force Fa is 490 N — these set the bearing load limits for belt drives or direct coupling with overhung loads. Exceeding these will shorten bearing life.
Shaft, flange, and mounting — Asian standard frame
Motor flange size is 180 mm with 4 mounting holes on an Asian standard flange pattern — this matches the common frame size for regional machine builders in Asia. Shaft diameter is 35.0 mm with a parallel key (key width 10.0 mm) and shaft length 79.0 mm, providing a standard keyed coupling interface. Overall dimensions: length 172.5 mm, width 172.5 mm, height 180 mm, depth 226.5 mm. The depth includes the rear connector protrusion — ensure at least 50 mm clearance behind the motor for cable bend radius and connector access. No holding brake (without), so the motor relies on the drive's holding brake or an external mechanical brake for vertical-axis holding. No second shaft end means no through-shaft for an external encoder or manual crank.
Feedback and electrical interface
23-bit optic multi-turn encoder provides 8388608 points per revolution — that is 23 bits of absolute position within one turn, plus multi-turn counts. This resolution supports sub-arc-minute positioning accuracy for indexing tables, gantries, and rotary axes. Back EMF constant is 63.98 V/krpm at 40 °C — at 1500 rpm the motor generates about 96 V line-to-line. The drive's DC bus must be high enough to overcome this voltage plus the IR drop at full load. Electrical connection uses 2 connectors (male/female) for power and feedback; the motor is 3-phase, 10-pole.
Sourced to order against BOM quantities through independent distribution. No official cross-reference or direct second-source exists for this specific encoder and flange variant.
