In 2005, BLDC motor controller was developed, improved and upgraded to address the existing weaknesses in several electric vehicles, vehicle design to meet the consumers and the increasing demand for vehicle performance. It avoids the same maximum rated power output of a long, sustained the same frequency to reduce the impact of the motor, motor coordination and other systems, electric cars and stable work, greatly extending the life of electric vehicles.

    Equipped with a BLDC motor controller for electric vehicles in the cycling process, the inverter controller and inverter composed of high-efficiency motor power system, take advantage of low current, high-torque theory, in the process of riding in a timely manner according to traffic and load to adjust the output power .

    This technology works, the electric car start, climbing, a small motor current, torque, and increases the climbing ability and more power; and on a level road, the standard load driving the motor to a small current, high efficiency work, so fast, low power consumption, extend the continued line mileage.

    Install the BLDC motor system of the electric car as long as a power supply and speed, the car was immediately driven, and demonstrated a remarkable strong force, and unlike most of the electric car start when they “struggle” was a difficult time crawling This is the BLDC motor technology advantage.

    In July 2005, the Group introduced three BLDC motor MACAT electric cars, are very popular. Taiwan Tianjin growth of electric cars with electronic features brushless motor control system — electronic CVT systems, but also uses the same technology. This new motor system increases the motor torque constant, reducing the overload point, the motor phase current context, to effectively improve the speed of the motor rated load point.

    2007 by Locomotive Co., Ltd. Qing long developed similar to the motorcycle gear with three power electric cars is based on such frequency control technology.

    This technology effectively improve the electric vehicle drive system features a certain extent, solve the electric vehicle the problem of poor climbing ability, and easy manipulation of the user, complete electric car downshift speed and overall performance has made great breakthroughs .

Based on the principle of rotation of the motor for the Fleming left hand rule, when a wire placed in a magnetic field, if the current through the wire, the wire will cut the wires generate the magnetic field lines move. Current into the coil creates a magnetic field using the current magnetic effect, the solenoid magnet at a fixed continuously rotating device that can convert electrical energy into mechanical energy. And a permanent magnet or by another group of the magnetic field generated by the coil to generate power bldc motor interaction principle is the stator does not move, the force generated by interaction of the rotor according to the direction of movement. bldc motor controller is on the alternating current through the stator windings, a rotating magnetic field, rotating magnetic field attracts the rotor rotates bldc motor with the basic structure include “armature”, “field magnet,” “slip ring”, “brush” . Armature: You can rotate around the axis of the soft iron core wound multi-turn coil. Field magnet: the strong magnetic field of permanent magnet or an electromagnet. Collector ring: coil about two to two semi-circular termination of slip ring, with the coil rotation for changing the current direction of the change to the device. Each half-circle rotation (180 degrees), the coil current to change direction once. Brushes: carbon usually made of slip ring brush contact with a fixed location to be connected to power.
