The Guanglu single-phase motor is ideal for those users who use smaller equipment and require less horsepower. This type of engine is used in residential, commercial and industrial environments and hardly needs maintenance. Guango’s single-phase motor is relatively cheap and only requires a stator. These motors can be designed to work on a single-phase or three-phase power supply.
Guanglu single phase motor
If you want to know which type of induction motor Guanglu single-phase motor is, you should get familiar with the types of single-phase electric motors.
Types of single-phase electric motors
Techfar induction motor is started using methods. Mechanical methods are not very practical, which is why the motor is temporarily started by converting it to a two-phase motor. Single-phase induction motors are divided into the following categories based on the auxiliary devices used to start the motor:
- Split-phase motor
- Capacitor-start motor
- Capacitor-start capacitor-run motor
- Permanent-split capacitor (PSC) motor
- Shaded-pole motor
Split phase induction motor
Split phase induction electric motor is also known as resistance start motor. This type of single-phase electric motor consists of a single-cage rotor (one shelf) and its stator has two coils. The main coil and the starter coil, which is also known as the auxiliary starter. Both coils are displaced by 90 degrees (like the coils of a two-phase induction motor). The main winding of the induction motor has very low resistance and high inductive reactance.
Characteristics of the split phase induction motor
The torque of a resistance split phase induction motor is about 1.5 times the full load torque. The maximum torque or output torque is about 2.5 times the full load torque at about 75% of synchronous speed. The split phase motor has a high starting current which is usually 7 to 8 times the full load value.
Application of single-phase split electric motor
Split phase motors are suitable for easy starting loads where starting frequency is limited and are very cheap.
Of these engines in the washing machine; air conditioning fans; food mixers; Mills, floor polishers, blowers, centrifugal pumps, are used in small drills, lathes, office machines, etc. Sometimes these motors are used for drives that need more than 1 kW.
Capacitor motors are motors that have a capacitor in their auxiliary winding circuit to create a greater phase difference between the current in the main and auxiliary coils. There are three types of capacitor motors:
Start capacitor induction motor
A capacitor start motor produces a much higher starting torque (ie 3.0 to 4 times the full load torque). To obtain a high starting torque, the value of the starting capacitor should be high and the resistance of the starting winding should be low. Due to the high VAR rating of the required capacitor, 250 µF grade electrolytic capacitors are used. The Cs capacitor has a lower rating. These motors are more expensive than split phase motors due to the additional cost of the capacitor.
The application of induction motor with start capacitor
These motors are used for heavy loads that require frequent starting. They are also used for pumps and compressors. Therefore, it is used as a compressor in refrigerators and air conditioners. Also, these single-phase motors are used for conveyors and some machines.
Double capacitor induction motor
This motor has a cage rotor and its stator has two coils called the main and auxiliary coils. They are 90 degrees apart in the coil. The motor uses two capacitors Cs and CR. In the initial stage, two capacitors are connected in parallel.
Application of two-capacitance induction electric motor
Two-capacitor motors are used for loads with higher inertia that require frequent starting. You can find these motors in pumping equipment, refrigeration, air compressors, etc.
Permanent split capacitor motor ( PSC )
These motors have a cage rotor and its rotor consists of two main and auxiliary windings. A single phase induction motor has only one capacitor C which is connected in series with the starter coil. Capacitor C is permanently connected in the circuit during startup and working conditions. These engines have advantages. For example, in these types of engines, there is no need for a centrifugal switch; This engine has a higher efficiency; Due to a permanently connected capacitor, it has a higher power factor and a higher output torque. However, these motors cannot be used for continuous operation.
Application of two-capacitance induction electric motor
These single-phase motors are used for fans and blowers of heaters and air conditioners. It can also be used to run refrigerator compressors as well as work with office machinery.
Grooved pole motor
The slotted pole motor is a simple type of self-starting single-phase induction motor that consists of a stator and a cage-type rotor. The stator consists of distinct poles. Each pole is grooved on the side and a copper ring is installed on the smaller side. This part is called the grooved pole. The coil is usually a single-turn coil and is known as a slotted coil.
Application of slotted pole motor
Slotted pole motors are used to drive devices that require low starting torque. These motors are very suitable for small devices such as relays, fans, etc. due to their low initial cost and simple setup. The most common applications of these motors are in hair dryers, fans of refrigeration and air conditioners, electronic equipment, cooling fans, etc.

The difference between single-phase Guanglu motor and three-phase electric motors
Electricity flows in a single-phase connection through a single-phase conductor. On the other hand, a three-phase connection consists of three independent conductors, which are required for electrical transmission. The voltage of a single-phase power supply system can be more than 230 volts.
Guanglu’s single-phase motor is reliable and is a better choice for small devices such as household appliances. At the same time, it changes the supply voltage of an AC power supply by a system. In power distribution, a single-phase motor uses phase and neutral wires. The phase wire carries the current load while the neutral wire provides a path for the current to return.
When the motor is connected to a single-phase power supply, the main winding carries alternating current. A single-phase motor requires additional circuitry to operate because the single-phase power supply connected to the AC motor does not produce a rotating magnetic field. The output power of a single-phase power supply is not constant, meaning that its supply voltage will rise and fall.
Guanglu three-phase electric motors are known as self-starting induction motors. These motors do not use capacitors, starter coils, centrifugal switches or other starting devices. Three-phase induction motors are used in industrial and commercial applications. These types of motors provide three alternating currents with three separate electrical services. The output power of a three-phase power remains constant and never reaches zero. It requires four wires, i.e. one neutral wire and three conductor wires. These three wires are 120 degrees apart from each other.
