If you are a motor manufacturer then you will obviously be aware of the difficulty in fitting the stator assembly into the motor enclosure. The Stack Assembly System for Motor provides the best solution to this problem. This system works on the principle of induction heating. The process is extremely  simple. Here the motor enclosure is inserted into the limb of the Stack Assembly Machine. The system is switched ‘ON’ and the enclosure is kept there for some time. This will causes the required expansion of the motor enclosure. Now the stator assembly can be easily inserted inside the motor enclosure The motor enclosure will contract and the stack assembly process is completed in a few minutes.

 

· 

The easiest way to fit the stator assembly into the motor enclosure

· High speed

· Lowest power consumption

· Accommodating various motor enclosure  sizes

· Automatic Control

· No color loss during the process

· Environmental Friendly

 

Advantages of the stack assembly system

 

Optimized Consistency

                 This type of heating eliminates the inconsistencies and quality issues associated with open flame, torch heating, Press fit and other methods. Once the system is properly calibrated and set up, there is no guess work or variation; the heating pattern is repeatable and consistent.

Maximized Productivity

                 Production rates can be maximized because induction works so quickly; heat is developed directly and instantly  inside the motor enclosure . Startup is virtually instantaneous; no warm up or cool down cycle is required. The induction heating process can be completed on the manufacturing floor, next to the winding machine or near the assembly table, instead of sending batches of parts to a remote furnace area or subcontractor.

Improved Product Quality

With induction, the part to be heated never comes into direct contact with a flame or other heating element; the heat is induced within the part itself by alternating electrical current. As a result, product warpage, distortion and reject rates are minimized.

Extended Fixture Life

This type of stack assembly process extends the life of the featuring and mechanical setup of the motor. There is no color loss during this process which is the case with furnace heating.

Environmentally Sound

This type of heating systems do not burn traditional fossil fuels; induction is a clean, non-polluting process which will help protect the environment. An induction system improves working conditions for your employees by eliminating smoke, waste heat, noxious emissions and loud noise. Heating is safe and efficient with no open flame to endanger the operator or obscure the process. Non-conductive materials are not affected and can be located in close proximity to the heating zone without damage.

Reduced Energy Consumption

Tired of increasing electricity bills? This uniquely energy-efficient process converts up to 90% of the energy expended energy into useful heat; batch furnaces are generally only 45% energy-efficient. And since induction requires no warm-up or cool-down cycle, stand-by heat losses are reduced to a bare minimum. The repeatability and consistency of the induction process make it highly compatible for this kind of mass production.

One stop solution

This system accommodates various motor enclosure  sizes. Thus this acts as a one stop solution for your many stack assembly problems.
