Magdyno Soft-geared Permanent Magnetic Brushless Motor And Its Advantage Comparisons in Light Electric Vehicle (LEV) Applications The synergetic effects of Magdyno permanent magnetic brushless motors with its soft-geared controller overcome the serious disadvantages of traditional motors. The applications, which are powered by Magdyno Soft-geared Permanent Magnetic Brushless Motor patented technology: “Stator winding for a variable speed brushless direct current (DC) motor”, “Soft-geared Controller Driven Power-train System and Its Application in LEVs”, take advantages of computer control engineering technology and Zero Commutation theory, achieving zero current gear shift. Magdyno has designed two series of soft-geared Permanent Magnetic Brushless Motors “*-geared” **0W~**0W *8V motors; and “*-geared” **0W *8V motors with their corresponding controllers as the power-train systems for electric bikes and electrolyzed motorcycles. The motor can be more efficiently operated in startup, acceleration and on the flat road because the overall speed range of the motor can be extended by switching the stator current to flow through one or more segments of the stator winding, to thereby dynamically adjust the number of "active" turns of the stator winding. It has a higher torque at low speeds, providing good starting and climbing performance of a vehicle incorporating such a motor. The motor can operate efficiently at moderate and high speeds, and can be controlled using a simple control system, thereby enabling simplified operation of an electric vehicle incorporating the motor.
