Brushless DC (BLDC) Electric Hub Motor
A Brushless Direct Current (BLDC) Electric Motor, also referred to as an electronically commutated motor, is a highly efficient synchronous motor powered by direct current (DC). Unlike traditional motors that rely on mechanical brushes, BLDC motors use an electronic controller to manage the current flow to the motor windings, generating rotating magnetic fields. These fields guide the permanent magnet rotor, resulting in smooth and precise motor operation.
The electronic controller is responsible for adjusting both the phase and amplitude of the current pulses, enabling accurate control over the motor’s speed and torque. This innovative design eliminates the need for a mechanical commutator, leading to several advantages, including higher efficiency, reduced maintenance, and enhanced performance, making BLDC motors ideal for a wide range of applications.
Permanent Magnet Synchronous Motor (PMSM)
PMSMs have permanent magnets on the rotor, and the stator windings create a rotating magnetic field. They offer high power density, efficiency, and excellent control, making them popular in electric vehicles
PMSMs are commonly used in electric and hybrid vehicles due to their high efficiency, compact size, and ability to provide high torque at low speeds. They contribute to improving the overall performance and range of electric vehicles while enabling regenerative braking for energy recovery

Motor Controller
A motor controller in an electric vehicle (EV) serves as the intelligent bridge between the battery and the motor, utilizing advanced power electronics and embedded microcomputers to convert stored energy into seamless motion.
Motor controllers receive input from key vehicle interfaces such as the throttle, brake, and forward/reverse controls. By processing these commands, they precisely regulate the motor’s speed, torque, direction, and overall power output, ensuring optimal performance for various driving conditions.
Low Voltage Application BLDC Controller
The BLDC motor operates with the help of the electronic commutation method instead of using mechanical brushes and commutators. The electronic controller switches the direction of the current into the stator’s winding which creates a magnetic field.
High Voltage PMSM Controller
High voltage PMSM controller in electric vehicles (EVs) play a critical role in managing the flow of electricity, ensuring that the vehicle operates at peak performance and efficiency. These controllers utilize advanced sensors and algorithms to make real-time, split-second decisions about how to distribute power to various components, such as the motor, battery, and auxiliary systems.
By precisely controlling the voltage and current, high voltage controllers enhance energy efficiency, improve vehicle range, and ensure the safe operation of high-powered EV systems. They are essential for delivering smooth, reliable performance in modern electric vehicles.
