What causes the motor to keep turning in the same direction?

When the contacts are reconnected, the commutator has reversed the current. So the side of the coil that was being pulled up before is now being pulled down. And vice versa. Therefore the coil keeps spinning in the same direction.

How can you reverse the direction of rotation of a DC motor?

The direction of rotation of a dc motor can be reversed:

By reversing the connections of both armature and the field windings with the supply.
By reducing the field flux.
By reversing the connections of either the armature or the field winding connection with the supply.

Can you change the polarity of a 12 volt motor?

The direction of rotation on a 12-volt motor will alternate with a change in polarity. Manually changing the polarity of a DC motor involves swapping the positive and negative cable positions on the battery.

Is there a way to reverse a 12 volt motor?

How to Reverse a 12 Volt Motor. Manually changing the polarity of a DC motor involves swapping the positive and negative cable positions on the battery. Removing installed wires connected between the motor and the battery to change rotation is cumbersome; you need another method of reversing the polarity of the motor.

Why does my 12 volt battery have reverse polarity?

There is an area in design where manufacturers are often at fault. It’s an ongoing trend in their design. It seems like 12-volt and 24-volt electronic equipment are more prone to damages. It is a bit ironic because most equipment is designed with some form of reverse polarity protection. This is usually in a diode and fuse form.

Can a 12 volt motor be used as a relay?

I have a 12 Volt motor that I attached to the lift wheel and to move the lift up and down the motor just has the polarity reversed. I want to be able to install a low volated remote control switch that I can operate from inside my boat while the 12 volt motor draws around 25 to 30 amps, thus the need for a relay.
