Pretty much. Theres around a dozen motor manufacturers. In my room I have 3 sunrise chairs. I have EMD, AMT, Linix, motors. So when you look at invacare its likely a similar picture. So the brand of chair is unimportand and the brand of motor more so.
Of these 3 sunrise powerchairs in my room, one is 8.5mph so these are less reliable due to higher loading greater currents. The 6mph 4 pole linix ones made in china are among the most reliable in the industry according to sunrise, and are found on many brands of chair. And the EMD ones are super strong, but I have a pile of dead ones because I abused them! So it depends!
So its not really about chair brands but the actual motor spec and the end users/programming settings etc. Any motor used hard dies faster. So a 4 pole HD 4mph motor will definitely live longer than a 8.5 mph motor on a heavy rehab chair.
