Product Description:

The EB-106-A-11 is a brushless explosion-proof motor developed by Kollmorgen within the EB Explosion Proof Motors series. It converts electrical input to rotational power for pumps, mixers, and actuators in hazardous areas. The design maintains compliance with explosion containment requirements.

The motor’s torque and electrical ratings set its steady operating window. A continuous stall torque of 2.20 N·m can be sustained while holding position without overheating, and this output is achieved with a continuous line current of 3.0 ARMS. When driven at the rated voltage of 230 VRMS, the shaft delivers a rated power of 1.2 HP; at the same speed, the running torque is 2.03 N·m, giving margin between running and stall conditions. The windings present a DC resistance of 6.50 Ω and an inductance of 37.5 mH, figures that influence drive tuning and limit current ripple. Back electromotive force is 43.7 VRMS/KRPM, so the drive must accommodate proportional voltage feedback as speed rises. For installations on higher-potential buses, the stator insulation tolerates a maximum line potential of 250 VRMS without partial-discharge concerns. A torque sensitivity of 0.723 N·m per ampere provides predictable gain for closed-loop controllers.

Transient performance is governed by the allowable peaks and thermal storage. During acceleration or shock loading, the rotor can deliver 6.18 N·m while the drive supplies a peak line current of 9.0 ARMS; both limits are intended for brief duty to prevent magnetic saturation. Rotor inertia is 0.0000765 kg·m², enabling fast response while minimizing overshoot in high-bandwidth position loops. Heat generated by these bursts is absorbed over a thermal time constant of 12 min, allowing intermittent overload without exceeding winding temperature limits. With a weight of 3.9 kg, the motor can be integrated on compact frames without imposing excessive structural load.
