The important characteristics of split phase induction […]
The important characteristics of split phase induction motor are given below,
The starting torque is 150 to 200 per cent of the full load torque with a starting current of 6 to 8 times the full load current.
Due to their low cost, split-phase induction motors are most popular single phase motors in the market.
Since the starting winding is made of fine wire, the current density is high and the winding heats up quickly. If the starting period exceeds 5 seconds, the winding may burn out unless the motor is protected by built-in-thermal relay. This motor is, therefore, suitable where starting periods are not frequent.
An important characteristic of these motors is that they are essentially constant-speed motors. The speed variation is 2-5% from no-load to full load. For this reason they are usually regarded as constant speed motors.
These motors are suitable where a moderate starting torque is required and where starting periods are infrequent e.g., to drive: (a) fans (b) washing machines (c) oil burners (d) small machine tools etc.
In the refrigerator working cycle, there are five primary elements available. The first one is a liquid refrigerant. The second one is a compressor that examines the path flow of refrigerant. The condenser coils, it’s placed on the outside of the fridge. The evaporator coils on the interior of the fridge and the last part are called expansion devices. A refrigerator is very familiar in the electronic segment of the Sathya Agencies Refrigerator Showrooms in Thoothukudi and Coimbatore.
The motor inside the hermetic compressor may be a capacitor start single phase induction motor. American refrigerators even have a little fan motor between the freezer and refrigerator compartment it's usually a shaded pole motor. Sathya Agencies is the leading Refrigerator Dealers in Coimbatore.
The compressor constricts the refrigerant vapor, increasing its pressure, and pushes it into the coils on the surface of the refrigerator
When the recent gas within the coils meets the cooler air temperature of the kitchen, it becomes a liquid. Now in liquid form at high, the refrigerant freezes down because it flows into the coils inside the freezer and therefore the fridge. The refrigerant absorbs the warmth inside the fridge, cooling down the air. Last, the refrigerant evaporates into a gas, then moves back to the compressor, where the cycle begins everywhere. It has made it possible for everybody to preserve food for days together. The cold temperature inside the refrigerator slows down the bacterial growth in food and thus preserves the food for extended. If you need to know more about this, Sathya has the finest Refrigerator Showroom and Dealers in Tuticorin
The working principle of the refrigerator is pretty simple. Gases get hotter once you compress them into less volume because you've got to figure to push their energetic molecules together. When you expand a gas, it's quickly ready to occupy far more volume.
Another variant, LG Power Cut Ever-cool may be a step further. It keeps the contents of the fridge also because the freezer cools for 7 hours during power cuts. The prices of these variants are more expensive than regular ones.
