Re: Denso window motor lockup when under load

We used the window motors last year for 4 wheel independent steering swerve drive. The locking pins caused friction and lockup. Lock up is most common when small changes are made at small PWM values. Note that our problems with the Denso motors did not totally disappear until we switched to victors. With the victors our steering worked perfect. There must be some PTC heating caused by the high frequency PWM of the jags. The 2 don't mix. A denso motor can be back driven with the locking pins removed. You will have to determine what is right for your application.
