If the motor will be rapidly decelerating a large inertial load from a high speed, care has to be taken to absorb the returned energy. The energy stored in the momentum of the load must be removed during deceleration and be safely dissipated. Because of its efficiency, the drive has no means of dissipating this energy so it returns it to the power supply. In effect, instead of drawing current from the power supply, the drive becomes a source of current itself. This current may charge the power supply capacitor to destructive voltage levels.

Also, the iron in the motor is subject to magnetic saturation, as well as having eddy current and hysteresis losses. Magnetic saturation sets a limit on current to torque proportionally while eddy current and hysteresis (iron losses) along with winding resistance (copper losses) cause motor heating.

An electric current is defined as free flow of electrons and the motivating force behind that free flow of electrons is called Voltage. Voltage is the measurement of potential energy that would move the electrons between two points. Voltage is the push that the electrons require to move within a circuit. Voltage is measured by Volt and Current is measured by Ampere.

This prevents you accidentally leaving something switched on which might cause the battery to go flat. The side and tail lights, however, which you may need to leave on when the car is parked, are always wired independently of the ignition switch.

For push on male to female mid-wire connectors, always use a shrink wrap over the connection to make sure it does not come un-connected. You can cut the shrink wrap to disconnect the wires later on.

This then is the motor’s natural speed-torque curve. Below a certain speed, called the corner speed, current would rise above the motor’s rated current, ultimately to destructive levels as the motor’s speed is reduced further.

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across those two points. It means that more the resistance lesser current would flow. I=V/R This would apply to any component of a circuit. For example conductors would increase the current flow and the inductors would decrease it.

Use a gauge of wire sufficient to carry the amperage load for the work it will be doing. Always use closed-end terminals, not the U type.
