Latest Patents

One of Tanaka's latest patents is a motor drive device designed to enhance the reliability of motor operation. This device addresses the issue of short-circuited phases in motor systems. When the upper arm of the U-phase fails due to a short circuit, the lower arms of the V-phase and W-phase are activated to maintain functionality. By turning on only the lower arm of the V-phase, a pathway for motor current is established, which reduces the current returning to the short-circuited phase. This innovative approach allows for continuous operation of the motor generator while preventing an increase in current through the damaged phase, enabling vehicles to run in limp mode. Another significant patent is for inert gas arc welding wire specifically designed for high chromium ferritic heat-resisting steel.
