Product Description:

The EB-202-B-11 is an explosion-proof brushless servo motor produced by Kollmorgen within the EB Explosion Proof Motors series. It is designed for motion axes that operate in hazardous or classified plant zones, allowing torque delivery without igniting surrounding vapors or dust. In automated machinery, the unit converts electrical energy into controlled rotational motion so actuators, pumps, or mixers can maintain precise speed and position while meeting safety codes for explosive atmospheres.

The motor can supply a continuous shaft load of 17.36 N-m while drawing a line current of 20.0 ARMS, and these ratings set the thermal limits for steady operation. Copper losses are tied to the armature's 0.382 ohms of DC resistance, and inductive reactance comes from the winding value of 9.0 mH. Together, these values produce a time constant of 23.6 ms, indicating how quickly current rises when a new command is issued. Back electromotive force develops at 51.6 V per krpm, so the drive must balance voltage headroom against commanded speed. Static friction of 0.490 N-m shows the breakaway effort required at start-up, while torque sensitivity of 0.853 N-m per amp helps tune current-loop gains.

The remaining performance data covers transient and mechanical limits. A peak capacity of 49.8 N-m covers acceleration or shock events, and routine operation tops out at 4000 rpm with a mechanical ceiling of 6200 rpm for overspeed contingencies. Rated output reaches 7.7 HP when the windings see 230 VRMS, while insulation tolerates a maximum line supply of 250 VRMS. The rotor inertia of 0.001028 kg·m² supports responsive positioning without excessive overshoot, and the assembly mass of 16.8 kg provides a stable mounting base that damps vibration in the surrounding structure.
