MOTOR DRIVE SYSTEM AND CONTROL METHOD OF SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240116366 titled 'MOTOR DRIVE SYSTEM AND CONTROL METHOD OF SAME

Simplified Explanation

The patent application describes a control method for a motor drive system that can switch between different drive modes based on the functionality of the inverters connected to the motor coils. When a second inverter malfunctions, the system switches to a different drive mode to continue operating the motor with relaxed output limits.

Explanation of the patent:

   * The system controls the operation of a motor drive system with multiple drive modes.
   * It monitors the functionality of the inverters connected to the motor coils.
   * If a second inverter malfunctions, the system switches to a different drive mode to maintain motor operation.
   * The new drive mode allows the motor to continue operating with relaxed output limits.

Potential Applications

The technology described in this patent application could be applied in various industries where motor drive systems are used, such as electric vehicles, industrial machinery, robotics, and renewable energy systems.

Problems Solved

1. Ensures continuous operation of the motor even if one of the inverters malfunctions. 2. Allows for a smooth transition between different drive modes to maintain motor performance.

Benefits

1. Increased reliability of motor drive systems. 2. Improved fault tolerance in case of inverter malfunctions. 3. Optimal performance with relaxed output limits in case of emergency situations.

Potential Commercial Applications

Optimized Motor Drive System with Inverter Fault Tolerance: Enhancing the reliability and performance of motor systems in various industries.

Possible Prior Art

One possible prior art could be the use of redundant inverters in motor drive systems to ensure continuous operation in case of inverter failures. However, the specific method of switching between different drive modes based on inverter functionality may be a novel aspect of this patent application.

The article does not provide information on how the switching between drive modes affects the efficiency of the motor drive system. This could be an important factor to consider when evaluating the practical implications of this technology.

What are the potential cost implications of implementing this technology in motor drive systems?

The cost of integrating the control method described in the patent application into existing motor drive systems is not discussed. Understanding the financial implications of adopting this technology could be crucial for businesses considering its implementation.

Original Abstract Submitted

in a control method of a motor drive system, when a first motor corresponding to a first drive wheel is being driven in a second drive mode among a first drive mode in which the first motor is driven by a first inverter of the motor drive system and connected to a first end of each of coils of the first motor and the second drive mode in which the first motor is driven by the first inverter and a second inverter connected to a second end of each of the coils and configured to selectively operate, whether or not the second inverter malfunctions is determined. when the second inverter malfunctions, a drive mode is changed so that the first motor is driven in the first drive mode. an output limit of the first motor in the first drive mode is relaxed.
