Introduction
In today’s society, with the increasing awareness of environmental protection and the growing demand for sustainable transportation solutions, electric tricycles have gradually become a popular choice for people to travel short distances and transport goods with their advantages of zero emissions, low cost, high efficiency and convenience. As one of the core components of electric tricycles, the performance and quality of the drive shaft DC motor (Transaxle DC Motor) are directly related to the overall performance and service life of the vehicle. This article will explore the relevant knowledge of the drive shaft DC motor in depth, including its working principle, type, performance characteristics, application scenarios, and market development status and trends, aiming to provide international wholesale buyers with valuable information to help them better understand and choose suitable motor products.
1. Working principle of drive shaft DC motor
The drive shaft DC motor is a device that converts electrical energy into mechanical energy. Its basic working principle follows the law of electromagnetic induction. When DC current passes through the stator winding of the motor, a magnetic field is generated, which interacts with the permanent magnets on the rotor to drive the rotor to rotate. The rotational motion of the rotor is transmitted to the wheels through the drive shaft to achieve the forward or backward movement of the vehicle.
In electric tricycles, the drive shaft DC motor is usually integrated with components such as the transmission and differential to form a compact transmission system, the so-called transaxle system. This design helps to improve space utilization, reduce the number of parts, reduce the weight of the vehicle, and improve transmission efficiency and reliability.
2. Types of drive shaft DC motors
Brushed DC motor:
Brushed DC motors are a traditional and common type of motor that uses brushes and commutators to achieve current commutation to keep the rotor rotating continuously. The advantages of this motor are low cost, simple control, and high starting torque. It is suitable for cost-sensitive applications that do not require extremely high motor performance, such as some basic electric tricycles.
However, the brushes will wear out during long-term use and need to be replaced regularly, otherwise it will affect the performance of the motor and even cause failures. In addition, the contact resistance and sparks between the brushes and the commutator will also limit the efficiency and maximum speed of the motor, and may generate electromagnetic interference.
Brushless DC motor:
Brushless DC motor (BLDC) uses electronic commutation technology to control the commutation of current through the motor controller, without brushes and commutators. This makes the brushless DC motor have higher efficiency, longer service life, lower maintenance cost, better speed stability and noise performance.
The brushless DC motor has a wide speed regulation range and can achieve precise speed control to meet the needs of different road conditions and load conditions. Its high efficiency characteristics mean that under the same input power, the brushless DC motor can output more mechanical energy, thereby extending the vehicle’s cruising range or improving its power performance. At present, brushless DC motors have been widely used in high-end electric tricycles and some applications with high performance and reliability requirements, such as freight and tourist versions of electric tricycles.
3. Performance characteristics of drive shaft DC motors
Power and torque output
Power is a key indicator to measure the motor’s ability to do work, usually in watts (W) or kilowatts (kW). For electric tricycles, the power of the motor directly affects its maximum speed, acceleration performance and load capacity. Generally speaking, a motor with a higher power can provide a stronger power output, making the vehicle easier to start, climb and accelerate.
Torque is the rotational torque generated when the motor output shaft rotates, which determines the vehicle’s traction and carrying capacity. High-torque motors can generate greater traction at low speeds, allowing tricycles to easily cope with various complex road conditions, such as starting on steep slopes and heavy-load transportation. For example, some electric tricycles specifically used for cargo transportation are equipped with a DC motor with a drive shaft that can reach a higher level of torque to meet the transportation needs of heavy goods.
