Product Description

138 Square Wave Brushless DC Motor | Original Standard English Product Introduction

Product Introduction

The 138 square wave motor is a brushless DC motor with high power, high speed and high torque. According to different stator structures, it is divided into two types: straight-slot stator and skewed-slot stator. The straight-slot motor features high torque and low speed, suitable for heavy cargo transportation. The skewed-slot motor has smooth startup and low noise, making it suitable for passenger tricycles such as rickshaws. The power range of the 138 square wave motor is 1000W~3000W.

Product Advantages

High Efficiency

1. High Power Density: The brushless DC motor uses permanent magnet excitation to provide greater power output under the same volume or weight, achieving higher efficiency. 2. Low Friction Loss: The brushless design eliminates the friction loss of brushes and commutators in traditional DC motors and improves the overall efficiency of the motor. With high efficiency, the 138 square wave motor operates with lower energy consumption and maintains long-term stability.

High Torque Output

1. High Torque Density: The strong magnetic field generated by the permanent magnets inside the brushless DC motor provides higher torque output under the same volume or weight. This feature makes the 138 square wave motor suitable for heavy-duty applications requiring high torque.

Excellent Operating Performance

1. Smooth Startup: Equipped with a skewed-slot stator, the 138 square wave motor ensures smooth startup, reduces initial impact and vibration, and improves riding comfort. 2. Low Noise: The brushless design eliminates noise caused by brushes and significantly reduces the overall operating noise of the motor. This feature is essential for applications requiring a low-noise environment, especially passenger tricycles.

Long Service Life

1. No Wearing Parts: The brushless design removes vulnerable parts such as brushes and commutators in traditional DC motors, extending the motor service life. 2. High Reliability: Commutation is controlled by an electronic controller, which simplifies mechanical components, reduces failure rates, and improves overall reliability.

Wide Application Range

1. Broad Power Range: The 138 square wave motor covers a power range from 1000W to 3000W, meeting various power requirements for different applications. 2. Versatile Applications: From heavy cargo transportation to passenger tricycles, the excellent performance of the 138 square wave motor makes it widely used in electric vehicles, industrial automation and transportation industries.
In conclusion, with high efficiency, high torque output, excellent operating performance, long service life and wide application range, the 138 square wave motor is an ideal choice for various applications requiring high-performance motors.
