Research on high-efficiency control of embedded magnet synchronous motors
Electrical and Electronics Engineering Program
SHINOHARA Atushi
Background and objectives of activities
More than half of the world's energy is consumed by motors, so reducing motor power consumption directly reduces energy consumption. For example, a 1% improvement in the efficiency of all motors can reduce the energy output of a nuclear power plant by one unit. In this laboratory, research is being conducted to realize higher efficiency of embedded magnet synchronous motors, which have the highest efficiency among all motors, and to apply them to industrial applications.
Summary of Activities
Embedded magnet synchronous motors are driven by sinusoidal currents, and their power and efficiency can be appropriately controlled by appropriately controlling the amplitude and phase of the currents. We will verify whether the high-efficiency control method developed using mathematical models and simulations is actually useful as a high-efficiency control method through experiments on actual devices using an experimental system like the one shown in the photo.
Expected Benefits
Expected that the efficiency of motors will be improved by applying the high efficiency control method to existing motors. If this improvement can be applied to all existing motors, a significant reduction in energy consumption can be expected.
