We have developed products that make it possible to make baking results undifferentiated and easily cope with complex cooking recipes

A brushless DC motor with high-end control technology is required to become a reality

You want to have a variety of cooking modes to experiment with a variety of cooking recipes

High performance is achieved by using a brushless DC motor that can accurately control operation and precise temperature

Taking advantage of the good control performance makes a significant contribution to the high performance of the oven

Japan Electco's brushless DC motor for ovens has the advantages of compact, energy-efficient, and accurate operation control compared to conventional hood motors in ovens. By using a brushless DC motor instead of a hot air motor on the back of the oven and a cooling fan and fan motor on the top of the oven, the inside of the oven of the same size and shape can be made more spacious, or the shape of the same size in the oven can be further reduced. Precise temperature control with accurate operation control enables a variety of cooking methods and prevents problems such as differences in bread baking results due to uneven temperature distribution inside the oven. In addition, this energy-efficient motor can easily respond to the trend of low power consumption of home appliances in Europe and other countries around the world.

Compared to conventional motors, it has excellent operation control and can realize a wide variety of cooking modes.

Even in the environment of high temperature and electromagnetic interference, there will be no faults, and it can be controlled accurately

Although brushless DC motors have an absolute technological advantage compared to AC hood motors, they cannot be directly used in ovens with temperatures up to 500 degrees Celsius due to the insufficient high temperature resistance of their internal control circuits. In order to ensure the high temperature resistance of the motor in the actual application environment, we have improved the insulation performance and thermal control system of the motor using CAE technology, and developed an optimal housing structure based on the shape of the heat dissipation impeller and the wind speed in the oven, which fully secures the high temperature resistance of the motor. At the same time, in view of the noise emitted by the relay when the heating tube is switched, which has been a technical problem that has plagued us for a long time, our company uses the method of physical filtering to filter the circuit, and further improves the stability of the control software, so as to solve the problem of motor failure due to relay noise. At the same time, we have started to improve both the hardware and software of the motor, so that the brushless DC motor has successfully replaced the AC hood motor used in the conventional oven.
