Abstract
An electric motor assembly device includes a carrier member with a central passage that receives a rotor shaft with a commutator. Brushes secured onto flexible, brush holders urge the brushes towards the central passage into a contact position with the commutator. The carrier member has mechanical elements for restraining the brush holders in an assembly position for assembly where the brushes clear the central passage and are protected against impact by the carrier member. This arrangement allows the rotor shaft to be introduced into the central passage of the carrier member without a risk of damaging the brushes. The brush holders are easily released automatically from the mechanical elements on the electric motor assembly device to bring the brushes into the contact position.
