Zhejiang Dagao Electric Motor Co., Ltd. (DAJI Group) is a well-known motor manufacturer that has been in business for 30 years. It was established back in 1988 with its headquarters situated in Shanghai, the international metropolis. The group has four manufacturing bases, including two in Shanghai and two in Zhejiang.
The company specializes in the manufacturing of various types of high-quality motors, including induction motors, which have become widely recognized for their efficiency, reliability, and durability. Induction motors are known for their simple construction, low cost, and ease of maintenance.
Induction motors consist of two main parts, namely the stator and rotor. The stator is the stationary part of the motor, which contains the casing, windings, and magnetic fields that induce an electric current in the rotor. The rotor, on the other hand, is the revolving part of the motor that converts electrical energy into mechanical energy. It rotates within the stator's magnetic field, creating a torque that drives the motor's output shaft.
There are two main types of rotors used in induction motors, including the squirrel cage rotor and wound rotor. The squirrel cage rotor is the most commonly used type of rotor in induction motors. It consists of a cylindrical core made of laminated steel and a series of parallel slots that contain aluminum or copper bars. The bars are short-circuited at the end by rings, forming a closed loop or "squirrel cage."
The wound rotor, on the other hand, is less commonly used and consists of a laminated steel core with slotted imports that carry a series of wire coils. The coils are connected to slip rings at the shaft ends, allowing external resistors to be inserted into the rotor circuit. The resistors control the rotor's impedance and speed, making it more adaptable to a wide range of industrial applications.
Induction motors are widely used in various industries, including mining, manufacturing, and power generation. They are known for their energy efficiency, low maintenance, and long lifespan. The motors are capable of operating in harsh conditions and are designed to withstand dust, dirt, and moisture.
In conclusion, Zhejiang Dagao Electric Motor Co., Ltd. Is an established and reputable motor manufacturer that produces high-quality motors, including induction motors. Induction motors are widely used in various industries and are known for their energy efficiency, reliability, and durability. They are simple to construct, require low maintenance, and offer a long lifespan. The company's commitment to excellence has helped them build a strong customer base and establish themselves as leaders in the industry.
