The wheeled motor drive used in the electric vehicles belongs to the distributed motor drive mode. The distributed motor drive mode is usually divided into wheel hub motor drive and wheel-side motor drive.
Both structures are used in current electric vehicles, but with the advent of compact planetary gear train, the high-speed inner rotor drive system has become more competitive in power density than the low-speed outer rotor drive system.
The main function of the AC induction motor control system is to provide variable voltage and variable frequency power supply for the motor, and its voltage and frequency can be adjusted according to a certain control strategy, so that the drive system has good torque-speed characteristics. The basic equation of AC induction motor speed control is
Light electric vehicles such as e-bikes, e-scooters, and low-speed electric cars that use Infineon’s brushless DC motor controllers with 24 V, 36 V, or 48 V battery capabilities exhibit increased battery life, longer operating range, and reduced charging times.
This technology is called vector control as the three-phase output current and voltage are expressed as vector in processing. The vector control is an advanced method to control the AC motor, in which the V/F control aims to maintain the motor flux constant, so that the motor maintains high efficiency.
Ideal applications for these low voltage motor controllers include cordless power tools, gardening products, and automated guided vehicles. IMD700A / IMD701A are the latest fully programmable motor controllers integrating the XMC1404 microcontroller with the 6EDL7141 3-phase gate driver IC in one package.
