Request a quote
The B-402-B-A3, produced by industrial automation leader Kollmorgen, is a highly efficient, low inertia servo motor designed for high acceleration rates. Its power capacity is 2.2 kW, and it reaches maximum speeds of 3000 rpm. Uniquely, this model can be fitted with front-mounted gearheads and an optional fail-safe brake, which provides 8 Nm of torque for emergency braking or static parking. Significant for its compact design, the B-402-B-A3 maintains a high torque-to-volume ratio and has a continuous torque of 7.4 Nm. Compliant with IP 65 and IP 67 sealing standards, the motor can function while immersed up to six feet underwater for 30 minutes. Brushless resolver feedback is shielded by the motor housing, while the explosion-proof design enables safe use in hazardous environments. Additional attributes include a DC tachometer, a 0.6% average to peak voltage ripple for smooth low-speed motion, and class H armature insulation for operation up to 180 ᵒC.
