What is the difference between series wound motors and permanent magnet motors?
Is one better than the other? A. An electric motor basically has two major parts, the stator and the rotor (or armature). It is the job of the stator to produce a magnetic field which will cause the rotor to rotate when an electric current flows through it. In a permanent magnet motor, the stator uses permanent magnets. This means the current drain on the battery is lower than series wound motors (which uses field coils in the stator). Permanent magnet motors are good for light and medium duty winches, but winching time and load has to be carefully monitored as they tend to overheat. Series wound motors are used in heavier duty winches, but tend to cost more. Q. Will my electrical system cope with the extra load of an electrical winch? A. For most pulls, yes. There a lot of people out there with one battery, stock alternator, and a winch. Keep in mind though that running a winch is the equivalent to moving your truck on the starter motor, there is a tremendous draw. Most electric winch
