SENSORLESS INDUCTION MOTOR SYSTEM AND CONTROL METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17980893 titled 'SENSORLESS INDUCTION MOTOR SYSTEM AND CONTROL METHOD THEREOF

Simplified Explanation

The abstract describes a sensorless induction motor system and a method of controlling it.

  • The system includes a control unit that applies sampling pulse voltages to the stator phases of the motor.
  • The control unit estimates the position of the rotor using a first rotor position vector that has the greatest deviation in the induced current.
  • It then compares the induced current deviation of a second rotor position vector with that of the first rotor position vector.
  • The control unit determines whether or not the permanent magnets of the motor are demagnetized based on this comparison.

Potential applications of this technology:

  • Industrial automation: This sensorless induction motor system can be used in various industrial automation applications, such as conveyor belts, pumps, and fans.
  • Electric vehicles: The system can be implemented in electric vehicle propulsion systems to improve motor control and efficiency.
  • Renewable energy: It can be used in wind turbines and solar tracking systems to optimize power generation.

Problems solved by this technology:

  • Eliminates the need for additional sensors: Traditional induction motor control systems require position sensors to determine the rotor position. This sensorless system eliminates the need for such sensors, reducing complexity and cost.
  • Detects demagnetization of permanent magnets: The system can detect if the permanent magnets in the motor are demagnetized, allowing for timely maintenance and preventing motor failure.

Benefits of this technology:

  • Cost-effective: By eliminating the need for additional sensors, the system reduces the overall cost of the motor control system.
  • Improved reliability: The ability to detect demagnetization of permanent magnets allows for proactive maintenance, preventing unexpected motor failures.
  • Enhanced efficiency: Accurate rotor position estimation improves motor control, leading to increased efficiency and performance.


Original Abstract Submitted

A sensorless induction motor system includes a control unit which applies a plurality of sampling pulse voltages to phases of the stator, estimates the position of a rotor through a first rotor position vector having the greatest deviation in an induced current, compares an induced current deviation of a second rotor position vector having a second greatest deviation of deviation of the induced current with that of a first rotor position vector, and determines whether or not permanent magnets are demagnetized; and a method of controlling the sensorless induction motor system.
