Internal Product Review
The EB-104-A-91-006 is a Kollmorgen explosion proof motor with 1.2 HP rated power and 5600 rpm rated speed. Strong torque production comes through 1.55 N-m stall torque at 40 C and 4.38 N-m peak torque, supporting demanding motion applications. A 10000 rpm mechanical limit makes this unit an excellent choice for high-speed hazardous-duty systems.

Product Description:
The EB-104-A-91-006 explosion-proof brushless motor is supplied by Kollmorgen within the EB Explosion Proof Motors series. The unit is intended for hazardous-location positioning or speed-regulated duties where ignition sources must be contained. As an automation element, it converts electrical energy from a matched drive into mechanical shaft rotation that can safely power mixers, conveyors, or pump assemblies located in flammable atmospheres. It weighs 3.2 kg, allowing compact integration where space is limited.
The motor has a rated shaft speed of 5600 rpm when the windings are excited at the nominal line potential of 230 VRMS. Under these conditions, it delivers 1.2 HP of mechanical power while drawing a continuous line current of 3.00 ARMS. Stall torque at 40 °C is 1.55 N-m, and torque rises proportionally with current at 0.512 N-m/ARMS. Back electromotive force is 31.0 V per krpm, which affects drive voltage selection together with the phase resistance of 5.30 ohms. The windings can accept up to 250 VRMS, but steady operation is limited to the rated voltage to control heat. Shaft speed must also remain below the mechanical limit of 10,000 rpm.
Transient demand is supported by a peak line current of 9.0 ARMS, allowing the motor to generate up to 4.38 N-m of dynamic torque without demagnetization. Magnetic field buildup is influenced by a line inductance of 28.1 mH, and the electrical time constant of 5.3 ms affects how quickly current rises during acceleration. The lightweight rotor has an inertia of 0.0000461 kg-m², which supports rapid speed changes while limiting reflected load. These characteristics suit motion systems that require fast indexing while still meeting explosion-proof operating requirements.
