2.9 kW at 1500 rpm — what the torque curve means for your axis
The BEH18MR2913CA6D delivers 18.46 Nm nominal torque at 1500 rpm, with a peak stall torque of 55.38 Nm — that is a 3:1 peak-to-continuous ratio, typical for a servo that needs to accelerate a load quickly then hold position without overshooting. The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution — enough resolution for sub-arcminute positioning on a rotary table or a direct-drive axis without gear multiplication.
IP67 and the Asian standard flange — mounting constraints
IP67 rating means the motor body and the connector interface survive washdown — the seal is at the housing, not the shaft lip, so keep the shaft extension dry if the environment is wet. Shaft is 35 mm diameter with a parallel key, 79 mm shaft length — no second shaft end, so no encoder-on-tail option without a separate shaft adapter.
Active production — sourcing posture
No official successor or cross-reference exists in the Lexium 18 family; this is the standard part for the 2.9 kW, 1500 rpm, 18.46 Nm duty point.
