An induction motor or asynchronous motor is an AC motor which works based on the principle of electromagnetic induction, that is, the rotor obtains a torque under the effect of a rotating magnetic field produced in the stator, and then the rotor can rotate. Normally, the rotor speed of the induction motor is not equal to the speed of the rotating magnetic field (synchronous speed), so the induction motor is also known as asynchronous motor. Based on the type of AC, there are single-phase and three-phase induction motors.
When buying an induction motor, the primary concerns are speed, voltage, torque and power. Other things you've got to take into consideration are working system, overload requirements, insulation class, protection class, moment of inertia, load, installation method, maintenance, ambient temperature, altitude, enclosure rating, outdoor environments, energy efficiency, etc. Now, ATO provides you with its reliable and economical induction motors and helps you make best choices in your purchases.
An induction motor using a single-phase AC power supply is called a 1-phase induction motor. Because single-phase induction motors only need single-phase alternating current, they are easy to use and widely used, and have the advantages of simple structure, low cost, low noise, and little interference to radio systems, so they are often used in household appliances and small power machinery with low power. Among them, such as electric fans, washing machines, refrigerators, air conditioners, range hoods, electric drills and medical equipment.
Three-phase induction motor is a kind of induction motor, which is powered by three-phase AC current. Compared with single-phase induction motors, three-phase induction motors have better running performance and can save various materials. Three-phase induction motor are mainly used in excavation, fluid transportation and other fields that need to provide power, such as machine tools, small and medium-sized steel rolling equipment, fans, pumps, light industrial machinery, metallurgy and mining machinery, etc.
Explosion-proof motor is a kind of motor that can be used in flammable and explosive places and does not produce electric sparks when running. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, in the textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine and other sectors are also widely used. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery, etc.
The brake motor is a fully enclosed self-fan-cooled squirrel cage type three-phase asynchronous motor with an additional disc type DC brake. It is composed of a DC disc electromagnetic brake motor attached between the rear end cover of the Y series motor and the fan. It is a derivative series of the Y series. It has the advantages of rapid braking, simple structure, high reliability and strong versatility. Brake motors are widely used in various mechanical equipment and transmission devices that require quick stop and accurate positioning.
A variable speed motor is a motor that changes the speed of the motor by changing the number of stages, voltage, current, frequency, etc. of the motor, so that the motor can achieve higher performance. Due to its excellent performance, variable speed motors have been widely used in steel, power stations, cables, chemicals, petroleum, cement, textiles, printing and dyeing, papermaking, machinery and other industrial sectors for stepless speed regulation of load machinery with constant torque or decreasing torque.
The stainless steel motor is designed to avoid flats, cracks and crevices, preventing the accumulation of foreign objects and bacteria. Its housing and cables can withstand daily high pressure, high temperature and aggressive chemical washdowns. The robust design means the motor can be cleaned without the need for guards and covers to protect it. These features ensure faster cleaning, higher uptime, and higher overall line equipment efficiency.
