What is the difference between a differential motor and a brushless motor? The rotor of a differential motor is a coil winding, connected to the power output shaft, and the stator is a permanent magnet; the rotor of a brushless motor is a permanent magnet, connected to the output shaft together with the housing, and the stator is a winding coil, without the commutation brushes used to change the electromagnetic field alternately in a differential motor, so it is called a brushless motor. It is called brushless motor.

Both differential motors and brushless motors are motors used to drive mechanical equipment, but their working principles and application scenarios are very different.

A differential motor is a special type of motor that enables a vehicle to steer by making the two wheels move at different speeds when turning. A differential motor is generally composed of an electric motor, a re-speeder, an interpolator, a fork and other components. Differential motors are mechanically efficient and have high steering accuracy, but can only be used for specific applications, such as for maintaining smooth and controlled steering while the vehicle is moving.

Brushless motors, on the other hand, are a common type of motor, also known as brushless DC motors (BLDC), which work by converting electrical energy into magnetic energy and mechanical motion to achieve work. It has the advantages of higher efficiency, lower noise and longer life than traditional DC motors, and is widely used in industry, household appliances, automobiles, aviation and other fields.

Therefore, differential motors and brushless motors are very different in terms of working principle, usage scenarios and application areas.

Differential motor and brushless motor which is better

Motors have an important role in many scenarios, especially in industrial applications, which is better: differential motors or motors? It is the most commonly used type of motor. So, differential motor and brushless First, from the motor structure, differential motor and ordinary motor structure is basically the same, only an additional reducer mounted on the motor shaft, while the brushless motor structure is more complex, consisting of three parts: brushless motor winding, position sensor and intelligent circuit controller, which makes its mechanical structure more complex.

Secondly, in terms of power output, brushless motors are mainly known for low noise, low heat emission, low loss and high performance, compared with traditional motors, the performance advantages of brushless motors are more obvious, while differential motors are limited by the reducer, and the power output will be reduced accordingly.

Furthermore, in terms of noise, temperature and heat generation, brushless motors have lower noise and lower heat generation, and the temperature control of brushless motors is more accurate, compared to differential motors, which will have higher heat generation and higher noise.

In addition, from the viewpoint of power transmission, brushless motor can achieve precise torque control, no maintenance, and more stable operation; while differential motor needs regular maintenance, and power transmission cannot meet the requirements of high precision.

Considering from the control system, brushless motor can realize precise position control and can realize higher precision motion control; while differential motor has more complex control system and more complicated motion control due to the limitation of reducer.

Finally, from the price consideration, brushless motor is more expensive, but its price is not much higher than the price of ordinary motor; while the price of differential motor is lower, but its maintenance cost is higher.

To sum up, brushless motors and differential motors have their own advantages and disadvantages, and the right type of motor should be selected according to the actual situation and application scenario. Brushless motors have superior performance and can achieve higher precision motion control, but are more expensive, while differential motors are less expensive but have poorer performance in terms of power output, noise, and temperature control. Therefore, users should choose the most suitable motor type according to their needs.
