This abuses the motor because it will dissipate four times as much heat as setting the current to its proper value. The actual increase in low-speed torque is considerably less than double because of magnetic saturation of the motor iron.

In this sort of a connection all the components would receive the same voltage, while the current would be divided amongst the components.

When fitting extra accessories, such as a rear window heater which consumes a heavy current, always wire it through the ignition switch. Some ancillary components can be operated without the ignition turned on by turning the switch to the "auxiliary" position. A radio is usually wired through this switch, so that it can be played with the engine off.

In the constant power region however, the drive is a voltage source so it introduces an additional 90 degree phase lag. The total phase lag now is 180 degrees, which is a setup for a sustained and building motor oscillation. This oscillation is commonly called mid-band instability or mid-band resonance.

As shown earlier, motor output power is proportional to power supply voltage, doubling the voltage doubles the output power. However, iron losses outpace motor power by increasing non-linearly with increasing power supply voltage. Eventually the point is reached where the iron losses are so great that the motor cannot dissipate the heat generated. In a way this is nature’s way of keeping someone from getting 500HP from a NEMA 23 motor by using a 10kV power supply.

By Lydie Honorine. Car Wiring. Published at Friday, January 19th 2018, 06:21:08 AM. Modern cars often need room for many wires in confined spaces. Some manufacturers now use printed circuits instead of bundles of wires, particularly at the rear of the instrument panel. Printed circuits are plastic sheets on which copper tracks have been "printed". Components are plugged directly into the tracks. A few modern cars have flexible printed circuits. The copper tracks are printed in ribbons of flexible plastic, which replace the whole wiring system.

Also make sure you connect the “ground” wire to the “grounding” terminal of the motor. Note that this must be the power supply ground conductor, not a wire leading to a ground rod nearby.
