Production of small precision Oriental BLDC motor, Tokyo, Japan, the plant's first three places in Kokubunjicho Takamatsu, Kagawa Prefecture, to start operations next spring. Medical devices and automatic teller machine (ATM) as a base for BLDC motor controller and mass production, the production system aims to enhance growth in demand-looking.
Increasing demand from emerging active capital investment in response to advances in medical devices, such as Europe, aims to increase production capacity.引Ki上Getai hopes to 1.5 times the current production of the future in the province.
The new plant, "Kokubunji Takamatsu Plant" (tentative title) is to build distribution center in Kokubunji Route No. 32 near the bypass. Reinforced two-story building, total floor space of 6,000 square meters. To begin in September and will be operational in May next year. The total project cost of approximately 1.7 billion yen.
The company has offices in 12 of the country, Western Takamatsu (Takamatsu), Tarumi Takamatsu (same) manufactures small BLDC motors used in medical devices in two plants in the prefecture. After processing the plant material in slack, finishing of the product is responsible for Western business. Slack in the six-story offices on each floor is divided into inefficient production lines had been outgrown in expansion of production.
Kokubunji office is planning to move the main features of the business slack, while providing an efficient production of a single floor and advance the automation of the plant.

BLDC motor controller by the converter
BLDC motor working principle
BLDC motor controller, including the Ministry of Power and Control Division as below: Power Ministry to provide three-phase power to the motor, control by the Ministry of the demand for converting the input power frequency. Department of directly to the DC power input (typically 24V) or AC (110V/220 V), if we have to first AC input is converted to DC by the converter. Either DC or AC input to input into the motor coil will be required before the DC voltage converted by the inverter 3-phase voltage to drive the motor. Inverter is generally composed of six power transistors. Six power transistors connected to the motor, as the control flow through the motor coil switch.
Make the motor turn up, the Ministry must first control the Hall IC to the motor rotor current location, then the stator winding in accordance with the decision on (or off) power transistor converter in order, so that current flows through the sequence motor coil forward (or reverse) rotating magnetic field, and interaction with the rotor magnet, so you can make the motor clockwise / counterclockwise rotation. When the rotor rotation to another group of Hall IC signal out of position, control of the Department again on the next set of power transistors, and so the motor can continue to rotate the same direction until the control of the Ministry decided to stop the rotor is shut down power transistor ; to reverse the rotor power transistor on the opposite order.

BLDC motor is a rotary machine
BLDC motor is a rotary machine, it will transform electrical energy into mechanical energy, which includes a solenoid winding to generate magnetic fields, or distribution of the stator windings and a rotating armature or rotor, a current through the wire and the magnetic field leaving the role of rotation, some types of these machines can be used for motors, generators can be used.
BLDC motor controller is to convert electrical energy into mechanical energy of the equipment, it is the use of power by the force coil in a magnetic field the phenomenon of rotation is made, distributed to each user at, BLDC motor power by using a different DC motor and AC motor into the power system Most of the motor AC motor, which can be synchronous or asynchronous motor motor (stator magnetic field speed and rotor speed is not in sync speed). Mainly by the motor stator and rotor components. Power wire in the magnetic field direction of movement by force and magnetic sense of direction with the current line (the magnetic field direction) direction of the. Motor works by magnetic force on the current role of the motor rotation.
