ABSTRACT:
A motor and associated gear system share an extended shaft axial with the motor. A rotor and a driving gear are attached to the shaft. Such an integral gearmotor concept minimizes coupling and sealing problems associated with prior art coupled motors and speed reducers. Particular housing features further enhance integrated advantages of the invention. Also, a reduction in the number of separate parts and use of a shim technique for establishing the stator/rotor air gap of the motor reduces prior art manufacturing costs associated with high precision borings while maintaining the accuracy of critical air gap characteristics. The shim feature of this invention is also equally and generally applicable to the establishment of air gaps in motors other than the present integral gearmotor.
