About Motor Parts and Accessories

Motor parts and motor accessories include products such as motor seals, commutators, laminations or laminated cores, carbon brushes, and electrical contacts. A motor seal is an electric motor part that provides a barrier between the motor and the fluid in the hydraulic reservoir or well. These motor parts and accessories transfer the torque that the motor generates and absorbs the downward thrust generated by the pump. Motor seals also allow the motor oil to expand and contract during motor operation. The motor seal drain line protects the motor and shaft seal by allowing oil from the motor housing to return to the hydraulic reservoir with minimal back pressure. Although hydraulic seals such as motor seals are generally reliable, products may fail due to excessive back pressure, high speeds, or pressure spikes. Improper remote valve synchronization and the dislodging of the return line quick coupler are common causes of pressure spikes.
