Overview

The three-phase induction motor solution focuses on the control of a three-phase induction motor, widely used in industrial pump, fan, and compressor applications. By providing inverter control sample software, Renesas aims to give the customer a head-start on inverter control development shortening the development time. Using this solution can simplify the development of inverter applications.

● Solution concept

three-phase- Induction-motor -solution

This solution controls an induction motor at rated speed under normal conditions, while it's controlled by high torque ratio to avoid slippage in temporary high load condition. Also, this solution can be flexible in the frequent change of rotation speed. Customers easily develop inverter control software for target applications by using this solution.

Rated speed = synchronous speed * (1-rated slippage)

Three-phase induction motor solution use vector control that expects high control accuracy and high response

● Solution Example

Issue: Unstable pressure output, due to inflexibility caused by ON/OFF control.

Solution: Variable control is achieved by inverter control. Stable control is also available by adding a detecting sensor in the inverter board.

Significant power consumption reduction by activating synchronous operation is also available.
  • Vector control sample software for a three-phase induction motor ready for customer evaluation
  • Significant time and cost savings for induction motor development
  • With speed sensorless vector control function, enable to reduce expensive speed sensors/BOM costs, and improve system reliability.
