Motor supplies and accessories help keep motors running, prevent or repair damage to motors, and adapt motors for use in specific tasks. Motor capacitors provide voltage to bring motors up to speed quickly at startup and can also improve their efficiency while running. Commutator maintenance products clean or polish the commutator in brush-style motors or generators to help extend their operating life. Motor mounting supplies help secure motors in place. Motor rotating switches respond to the centrifugal force of the motor shaft to open and close. Rainshields stop liquids or small solids from getting inside motors and causing potential damage. Power transmission accessories allow motors to transmit power to equipment.
