Winches have been used since ancient times to lift heavy objects by winding up or letting out a rope, cable, or wire. It is this same basic principle that can be found in today's winch motors, though more sophisticated parts are involved to make the process automatic. Below, learn more about how these motors work, common types, and signs you may need winch repair.

How Winch Motors Work

The fundamental components of a winch motor are a cable wire, a drum, the electric motor itself, and the gear train. When electricity to the motor is turned on, opposing poles spin a magnet that powers the motor and turns the winch.

The cable wire then winds or unwinds from the drum. The gear train is a mechanical system of gears with teeth that produce a maximum amount of torque; this allows the winch motor to pull up heavy loads.

Types

All winch motors contain a set of coils, known as an armature. In a permanent magnet motor, there is a set of magnets inside the armature. They produce a field that spins the armature and brings power to the engine.

A series-wound motor doesn't have magnets inside the armature but inside another set of coils, called field coils. These are attached directly to the armature, and when they spin, they create a gradual magnetic field that then spins the armature and powers the engine.

Signs You Need Winch Repair

If your motor runs in only one direction—limited to only winding or unwinding—it could be a sign of a faulty switch or coil. A drum that won't turn is another common issue. If the drum won't turn but the motor runs, there's likely a problem with the clutch.

A motor that won't turn on at all can have any number of potential causes, including loose connections or wiring, a broken switch, a defective coil, or dirty components.
