Product Description:

The EB-606-A-11-001 explosion-proof motor is produced by Kollmorgen and belongs to the EB Explosion Proof Motors series. It is a brushless synchronous design engineered for hazardous industrial zones where ignitable vapors may surround rotating equipment. By pairing with a compatible servo drive, the unit converts electrical power into controlled shaft torque for pumps, agitators, and material-handling conveyors that must keep running even when the atmosphere cannot be purged. The construction isolates potential ignition sources and maintains internal clearances that prevent flame transmission.

Under steady load, the motor delivers a continuous stall torque of 44.8 N·m while drawing a continuous line current of 20.0 Arms. At the rated speed of 1550 rpm, this torque corresponds to 6.6 kW of mechanical output, and the winding develops a back electromotive force of 135 Vrms per kRPM in proportion to shaft velocity. When short-term acceleration is required, the drive can supply a peak line current of 62.0 Arms. The 230 Vrms rating matches common industrial inverters, while a torque constant of 2.24 N·m/Arms enables predictable current-controlled torque production across the full operating range.

For overload events, the shaft can develop a peak torque of 132.0 N·m, a level supported by six rotor poles and a rotor inertia of 0.00304 kg·m² that balances quick response with torsional stability. The stator’s phase-to-phase inductance is 15.6 mH and its winding resistance is 0.500 Ω; these electrical values influence current response and drive bandwidth. Mechanically, the housing measures 464.7 mm in overall length, the factory-fitted leads extend 609 mm, and the assembled motor weighs 29.9 kg, which helps when planning installation inside flameproof enclosures with limited mounting space.
