Notes on this data
Product page quotes continuous stall torque 0.65-72.1 Nm; RevG catalog system tables give 72.8 Nm max (AKM2G-74P with AKD 240 V) - catalog figure used. Peak 164 Nm (AKM2G-74P/74Q with AKD-x04807). Max mechanical speed 8000 rpm for 2x/3x frames, 6000 rpm for 4x-7x. 11.8 kW is AKM2G-74R at 400 V. Catalog lists connector IP65; overall motor IP from product page.
