Patent ID: 8544520

Claim:
A vehicle wheel service machine, in particular a tyre changing machine, comprising: a rim mounting device ( 2 ) having a rotatable shaft ( 21 ) and a rim mounting plate ( 23 ) connected rotationally fixed to the shaft ( 21 ), a motor driven via a driving circuit and adapted to drive the rotatable shaft ( 21 ) of the rim mounting device ( 2 ), a first detector adapted to detect the rotational speed of the rim mounting plate ( 23 ), a second detector adapted to detect the rotational speed of a wheel ( 1 ) mounted to the rim mounting plate ( 23 ), and a controller adapted to receive and compare output signals from the first and second detectors, wherein the controller outputs a control signal to the driving circuit of the motor to adapt the driving of the motor so that the rotational speed of the rim mounting plate ( 23 ) and the rotational speed of the wheel ( 1 ) are approximated to each other.
