A direct drive motor is one which uses the force coming from an electric motor with no losses. The power comes from an electric motor and it is supplied to a drive shaft with no loss. One of the advantages of a direct drive is that the motor is free to move in any direction and at any speed so that the motor can be used to turn the wheel and create torque. This means that the wheel turns faster with the motor than without it. This is also used to increase fuel efficiency.
Some disadvantages of using a drive motor are that the motor itself is more expensive than using an electric motor. The motor needs to have a lower ampere rating in order to avoid overheating, but this should only be done if necessary. Another disadvantage of the motor is that the power cord is longer which makes the car heavier and not as portable as electric motors.
Another advantage of a direct motor is that there are less components required to put it together. A controller for the motor is needed and there are fewer parts to put together. Also, the motor is much easier to install because there are fewer parts and the cables are shorter. These two things combine to make it easier to install a direct drive motor and easier to use. As the number of vehicles increased the need for direct motor engines diminished because more power could be produced with smaller engines.
There are a variety of applications for a direct motor engine. It is now widely used on golf carts, sail boats and even cars. However, some of these vehicles have been retrofitted with an electric motor and they can still be operated with the use of a direct drive motor.
A direct drive motor is also being used in military vehicles. The motor is small enough to fit on top of a tank or to mount on top of the vehicle. In the military, the motor can also be mounted on a vehicle which is moving to simulate an aircraft and it can simulate a rotor blades. The rotor is not very long and the motor is not much bigger than that of an ordinary engine so it is not too difficult to build the rotor.
One of the reasons that military uses a motor like this is that the motor can provide greater speeds and torque than would be possible with an electric motor. The engine has to be smaller and lighter so that it can be moved around easily. Because the vehicle is being moved, the engine can be used to accelerate and decelerate the vehicle. The speed of the vehicle can vary depending on what is needed. and because it is not an electric motor being attached to an engine then the speed can vary because of the environment and the speed of the moving object.
