Abstract
A wheel balancer is provided that includes a shaft adapted for receiving a wheel/tire assembly, the shaft having a longitudinal axis and being rotatable about the axis so as to rotate a wheel/tire assembly removably mounted thereon, a rotation sensor for measuring rotation of the shaft about its longitudinal axis, a vibration sensor operatively connected to the shaft for measuring vibrations resulting from imbalance in the wheel/tire assembly and a motor operatively connected to the shaft for rotating the shaft about its longitudinal axis, thereby to rotate the wheel/tire assembly. A control circuit is also provided for controlling the application of power to the motor. The wheel balancer also includes an assembly for measuring runout of the rim of the wheel/tire assembly, the control circuit being responsive to a rim runout measurement signal to apply power to the motor such that the wheel/tire assembly rotates at a slow, controlled speed during measurement of the rim runout.
