What’s the difference between EV hub motor and BLDC motor

Motors are a critical component of modern technology. They’re used in everything from domestic appliances to factories, electric vehicles, and aircraft, among others. The types of motors used in different applications vary based on specific needs and requirements. Two of the common types of motors used are the EV hub motor and BLDC motor. These motors are used in different applications, but they have some similarities and differences.

We aim to provide an overview of the differences and applications of EV hub motors and BLDC motors. It will also discuss the application of neodymium iron boron (NdFeB) magnets in these two types of motors. Will also highlight the performance requirements and advantages of NdFeB magnets used in motor manufacturing by Zhejiang Zhongke Magnetic Industry Co., Ltd.

The Difference between EV Hub Motor and BLDC Motor

The EV hub motor and BLDC motor are both electric motors, and they have a lot of similarities. For instance, both are brushless motors, meaning they don't have carbon brushes and commutation. Instead, they rely on a control system to switch the stator electric current and generate torque. They also have similar construction with stator and rotor parts.

However, one of the significant differences between the two types of motor is their application. EV hub motors are specifically meant for electric vehicles. They’re compact and efficient for use as automotive power. They’re lightweight and can be mounted to the vehicle’s wheel hub, which eliminates the need for a transmission system. The motor’s location at the wheel also increases the vehicle’s performance and stability.

On the other hand, BLDC motors have more versatile applications, such as in industrial machines, electric bikes, drones, HVAC systems, and others. They’re relatively more powerful and have higher torque capabilities than the EV hub motor. Moreover, they’re not mounted to the wheels but to a dedicated gear system. They’re also less compact, and their installation requires more space than EV hub motors.

The Use of NdFeB Magnets in EV Hub Motor and BLDC Motor

NdFeB magnets are widely used in modern motor manufacturing due to their superior magnetic characteristics over other magnetic materials. They have high coercivity, magnetic energy, and temperature stability, making them the ideal material for motor applications. These features contribute significantly to the motor’s performance, especially when used in EV hub motors and BLDC motors.

EV hub motors and BLDC motors require high-performance magnets to generate the required torque without power loss. NdFeB magnets offer high magnetic flux density and high coercivity, making them capable of generating the high torque needed by the motor.

For instance, EV hub motors require NdFeB magnets with high magnetic flux density to provide the necessary driving power and improve torque. The magnets must also be resistant to high temperature to withstand the heat generated by the motor during operation.

Similarly, BLDC motors require NdFeB magnets with high coercivity to maintain magnetization. The magnets must be capable of operating within a wide range of temperature without demagnetization or power loss. These properties make NdFeB magnets the ideal material for BLDC motor applications.
