Autonomous Velocity Motors

One of the biggest problems with any device that needs an electric motor is the faster a motor turns and the more torque that is required, the more current and/or voltage is required to run it which limits the time a motor can run from a stored energy source like a battery. My motor modification enables a motor to run at variable speeds and produce a high torque while maintaining a fixed current and voltage.

By extending the time a motor can run from a battery will enable any device needing a motor to run with fewer battery changes and longer intervals needed for recharging the battery. Because the motor runs, using milliamps and low voltage, a solar cell can be used for the power source. Since a motor runs on electricity there are no emissions that pollute the environment which will help reduce green house emissions.

Because this motor is a more efficient design that uses less energy to run it could potentially replace most if not all electric motors in the next 10 to 20 years if production can keep up with demand.

With the advent of a different kind of electromagnet for use in a motor, and the placement of the permanent magnets in the motor. I have found a way to better utilize the magnetic and electromagnetic fields of force in a motor that keeps current (Mila-Amps) and voltage loads constant regardless of speed and load. The Cad drawings shown are a basic example of how the motor can be configured. There are 2 key design elements that will not be shown in any detail until a patent can be obtained.

Using a simple variable speed LC Oscillator for frequency input to a stamp microcontroller for clock speed and an opto-isolator circuit to control the transistor array that turns the electromagnet elements on and off for rotation direction and speed simplifies the basic construction of the motor. With a few design alterations this electric motor could be manufactured using the same methods as most brushless motors in production today.

The cost of manufacturing would initially be about third more expensive than current motor designs, but the lower power consumption will out way the additional motor costs with reduced cost needs for batteries. Over time and mass production, the production costs will go down.
