The motor I purchased was for my ST1500SF model. The package came way before I expected it and It was packed very well with no damage and fit perfectly in my mail box rather than on my doorstep. The problem that I had was that, the floating cylinder housing or rotor wasn’t pressed all the way onto the stator leaving a 1/8” gap on the top end while the bottom rotor shaft was sandwiched onto the casing. That small clearance made the difference when secured to the outside casing. So it smoked then stopped leaving a perfect little circle at the bottom of the casing from the end of the rotor shaft. Luckily I was able to disassemble, figure out the problem and press the rotor all the way flush with the stator and reassemble. Overall so far so good motor, just beware and look closely of course to matching the one you are replacing.

The original motor went bad. When I pressed the trigger, the head would only twitch. I had about a year left on my 5 year warranty, but Ego Customer service recommended changing the cutting head and said that I could end up paying for the repair if it was sent to a repair center, which would require that I send a battery and charger along with the trimmer. Sounds like neither service or repair knows what they are doing. Soldering the leads from the new motor to the existing cable was a challenge, the wires need to be short to fit inside the tube and motor cover. But it worked. You need Power+Parts because your Ego warranty is likely worthless! Ego Customer service may recommend you replace accessories that are not the source of the problem. It's a shame because it's such a handy trimmer.

Quick service. Right part. Unit back in service say no more.

Works as intended. Arrived quickly and kept the work flowing.
