Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

A starter motor connected to a power supply and operable to start an internal combustion engine includes an outer housing and a solid state switching device associated with the outer housing. The outer housing encloses a commutator and a series of brushes. The solid state switching device is movable between an open position and a closed position. The current flow from the power supply through the commutator is prevented when the solid state switching device is in the open position.

A generator system having a dynamo that contains an armature, a stator and a housing. The armature rotates about a first axis of rotation. The stator is concentrically positioned around the armature. Both the armature and the stator are free to rotate in opposite directions about the first axis of rotation. The housing of the dynamo is connected to a motor that can rotate the dynamo around a second axis of rotation. There is an angle of inclination between the first axis of rotation and the second axis of rotation. This angle of inclination is selectively altered during operation. By changing the angle of inclination between the two axes of rotation, a precession can be created that adds rotational energy to both the armature and the stator. This increases the output of the dynamo and creates a highly efficient electrical generator.

An electric motor, an end cap thereof and a manufacturing method of the end cap are provided. The end cap includes an insulating body and a filter circuit board mounted to the insulating body. The filter circuit board includes at least two power conductors for receiving an external power source, an insulating support frame integral with the at least two power conductors, and at least one filter element. One end of the at least one filter element is connected to a corresponding power conductor, and the other end of the at least one filter element is grounded.

A power tool with a motor which is rotatable in a forward direction and a reverse direction. A tool holder is driven by the motor. The power tool has a user operable trigger for operating the motor, a reversing switch for choosing the direction of rotation of the motor and a controller. The controller determines a direction of rotation of the motor based on a characteristic of the motor.
