DRIVE DEVICE, DRIVE METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18207354 titled 'DRIVE DEVICE, DRIVE METHOD, AND STORAGE MEDIUM

Simplified Explanation

The abstract describes a drive device that includes an electric motor, a power control device, an oil circuit for cooling the motor, a water circuit for cooling the power control device, a heat exchanger for exchanging heat between the oil and water circuits, and a control device. The control device drives the power control device for heat generation when the temperature of the oil is equal to or lower than a certain threshold value.

  • The drive device includes an electric motor, power control device, oil circuit, water circuit, heat exchanger, and control device.
  • The oil circuit cools the electric motor with oil, while the water circuit cools the power control device with water.
  • The heat exchanger exchanges heat between the oil circuit and water circuit.
  • The control device drives the power control device to generate heat when the oil temperature is below a certain threshold.

Potential applications of this technology:

  • Automotive industry: The drive device can be used in electric vehicles to efficiently cool the motor and power control device, improving overall performance and longevity.
  • Industrial machinery: The drive device can be implemented in various industrial machines that require efficient cooling of the motor and power control device.

Problems solved by this technology:

  • Overheating: The drive device effectively cools both the motor and power control device, preventing overheating and potential damage.
  • Energy efficiency: The heat exchanger allows for efficient heat transfer between the oil and water circuits, reducing energy consumption.

Benefits of this technology:

  • Improved performance: The drive device ensures optimal temperature control, leading to improved performance and reliability of the motor and power control device.
  • Extended lifespan: By preventing overheating, the drive device helps prolong the lifespan of the motor and power control device.
  • Energy savings: The efficient heat exchange provided by the heat exchanger reduces energy consumption, resulting in cost savings.


Original Abstract Submitted

A drive device is provided. The drive device includes an electric motor, a power control device, an oil circuit that cools the electric motor with oil, a water circuit that cools the power control device with water, a heat exchanger that exchanges heat between the oil circuit and the water circuit, and a control device. The control device drives the power control device for heat generation, when a temperature regarding the oil is equal to or lower than a first threshold value.
