Abstract
A method and apparatus for balancing of a motor armature and fan coupled thereto is disclosed. The apparatus includes a pair of spaced end brackets for supporting an armature of the motor and the fan for rotary movement. At least one motor bracket is coupled between the end brackets and includes means for detachably mounting a set of field coils for the motor thereon. The motor bracket further includes a recess therein which, when the set of field coils is detached from the motor bracket, exposes the armature to permit the armature and fan to be rotated as a unit so that the balance of the unit can be determined. The method and apparatus are particularly adavantageous for balancing a motor-fan system in which the motor is of the split-field coil type.
