What does the protection level of the motor IP44 represent?

The protection level adopts the IP rating standard recommended by the International Electrotechnical Commission (IEC), and the level is different for different installation sites, which is called "IP44". You can refer to the instructions below to select the details. In the rating standard, " is a two-digit number, with the first digit indicating the degree of protection against solids and the second digit indicating the level of protection against liquids.

There are 7 levels of solid protection, which are represented by 0-6; There are 9 levels of liquid protection, which are expressed from 0 to 8. The specific instructions are as follows: Solid protection level IP level in this paragraph:

Brief description Definition 0: Unprotected No special protection 1: Solid protection of 50mm Large parts of the human body such as hands (unprotected from conscious contact), solid with a diameter of 50mm 2:

Solid 12mm resistant fingers or the like, no more than 80mm in length, solid with a diameter of more than 12mm 3: Solid with a diameter or thickness greater than tools, wires, etc., Solid with a diameter of 4: Solid with a diameter greater than 1mm Wire or sheet with a diameter of more than 1mm, Solid with a diameter of more than 1mm 5:

Dustproof does not prevent all dust from entering, but the amount of entry does not hinder the normal operation of the equipment 6: Dust-tight No dust ingress This paragraph liquid protection level: IP level:

Brief Description Definition 0: No protection No specific protection 1: Drip proof Vertical dripping should have no harmful effects 2:

15° drip-proof When the device is at an angle of 15° to the vertical line, the dripping water should have no harmful effects 3: Waterproof The drenching water in the range of 60° angle to the vertical line should have no harmful effects 4: Splash-proof Splashing water in any direction should have no harmful effects 5:

Anti-flushing There should be no harmful effects on flushing in any direction 6: Prevent violent waves The amount of water entering the casing during violent waves or strong flushing should have no harmful effects 7: Anti-flooding After immersion in the water at the specified pressure for a specified time, the amount of water entering should have no harmful effects 8:

Anti-diving It can be dived for a long time, completely sealed, and the water ingress does not have a harmful effect.

The IP44 motor is a general protection motor, which can prevent splashing water and solids of more than 1 mm from entering.

The protection level of the motor is IP23, which means that it can prevent solid foreign objects with a diameter greater than 12mm from entering the shell, and can prevent fingers from touching the live or moving parts of the shell, and the water within the range of 60o angles with the plumb line should not directly enter the inside of the motor.

The first digit 2 represents: protection against solids larger than 12mm, can prevent solid foreign objects with a diameter greater than 12mm from entering the shell. It prevents fingers from touching the charged or moving parts of the case.

The second digit of the number 3 represents: drip-proof , dripping water within a range of 15o angles with the plumb line, which should not directly enter the inside of the motor.

The first digit) is the rating and definition of the first digit of the protection level Abbreviated as the definition.

0 Unprotected There is no specialized protection.

1. Protect against solid bodies larger than 50mm from entering the shell. It prevents a large part of the human body (such as a hand) from accidentally or accidentally touching the charged or moving parts of the shell, but does not prevent conscious access to these parts.

2. Protect solids larger than 12mm from entering the shell with a diameter of 12mm. It prevents fingers from touching the charged or moving parts of the case.

3. Protect solids larger than the diameter of the solid foreign matter can prevent the diameter of the solid foreign matter into the shell. It can prevent tools and metal wires with large thickness or diameter from touching the charged or moving parts of the bulk shell.

4. Protect solids larger than 1mm from solid foreign matter with a diameter greater than 1mm from entering the shell. It can prevent wires or strips with a diameter or thickness greater than 1mm from touching the live or running parts of the shell.

5. Dustproof It can prevent dust from entering to the extent that it affects the normal operation of the product, and completely prevents it from touching the live or moving parts in the shell.

6 Dust Tightness It can completely prevent dust from entering the shell and completely prevent it from touching the live or moving parts of the shell.

P (ingress protection) protection level.

The system was drafted by the IEC. The degree of protection is adopted by the International Electrotechnical Commission.

IEC) recommended IP rating standards, different installation sites, the level is different. IP classifies luminaires according to their dust-proof and moisture-proof properties. The external objects referred to here, including tools, and human fingers should not touch the live part of the lamp to avoid electric shock.

Meaning of IP44 representation:

1. Prevent tools, wires and similar small foreign objects with a diameter or thickness greater from invading and contacting the internal parts of electrical appliances.

2. Prevent water splashing from all directions from invading electrical appliances and causing damage.

The level of protection is mostly expressed by two numbers followed by IP, and the number is used to clarify the level of protection.

The first number indicates the extent to which the device is resistant to fine dust, or the extent to which people are protected from the hazards of burial in a curved sealed environment. i stands for the level of protection against the ingress of solid foreign matter, and the highest level is 6;

The second number indicates how waterproof the device is. P stands for the level of protection against water ingress, and the highest level is 8.

For example, the protection level of the motor is IP65, the protection level is IP55 and so on.

The protection level adopts the IP rating standard recommended by the International Electrotechnical Commission (IEC), and the level is different for different installation sites, which is called "IP44". You can refer to the instructions below to select the details. In the grading standard, " is a two-digit number, the first digit indicates the degree of protection against solids, and the second brightness indicates the level of protection against liquids.

There are 7 levels of solid protection, which are represented by 0-6; There are 9 levels of protection against liquids, which are expressed from 0 to 8. The specific instructions are as follows: Solid protection level IP level in this paragraph:

Anti-diving It can be dived for a long time, completely sealed, and the water ingress does not have a harmful effect.

The motor protection level includes waterproof grade, explosion-proof grade and insulation grade.

The IP (IngressProtection) protection rating system was drafted by the International Electronic Technical Commission (IEC). Electrical appliances are graded according to their dust-proof and moisture-proof characteristics.

The IP protection level is composed of two numbers, the first number indicates the level of dust removal and prevention of foreign objects intrusion of the lamp, and the second number indicates the airtightness of the lamp against moisture and waterproof intrusion, and the larger the number, the higher the protection level.

Motor classification: 1. According to the working power supply, it can be divided into DC motor and AC motor, of which AC motor is divided into single-phase and three-phase.

2. According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor. The rotor speed of an asynchronous motor is always slightly lower than the synchronization rate of the rotating magnetic field. The rotor speed of the synchronous motor is independent of the load, and the synchronization rate is always maintained.

3. According to the starting and operation modes, it can be divided into capacitor start single-phase asynchronous motor, capacitor rushing single-phase asynchronous motor, capacitor starting single-phase asynchronous motor and separate single-phase asynchronous motor.

4. According to the use classification, it can be divided into drive and control. Drive motors can be divided into electric tool motors, motors for home appliances and motors for other general small mechanical equipment. The control motor is divided into stepping, servo, speed measurement, etc. <>
