7.5HP Air Compressor Electric Motor 3450RPM 184T Frame 230V Single Phase 2-3/4" Shaft Length

How to Choose the Right Motor for Your Application

1.Amperage. This is your electric motors TRUE power rating. Please make sure your FL amp (FULL LOAD) rating on the motor you're replacing is within 10% of the FL Amp rating of the motor you intend to buy.
2.Frame Size. The frame not only constitutes the bolt pattern, it also depicts the overall size and torque. The larger the frame, the stronger the motor. It's extremely important that you replace it with the same frame size. Improperly sized motors will inevitably result in motor failures.
3.Phase and Voltage. If your machine requires a 230V electric motor on single phase power. You would want to incorporate a 1-phase 230V AC electric motor for your application. 230V electric motors cannot handle voltages less than 208V. They will run too hot and you will experience motor failure.
4. RPM. Matching up the RPM is quite important. The wrong speed can damage your pump. The RPM does not have to match exactly, but you do need to be the neighborhood. For example: 3510rpm, 3550rpm, 3450rpm are all the same. They are all fall under the umbrella of whats known as 3600RPM motors.
5. Shaft Diameter. With a tape measure. Measure the outside diameter on your electric motors shaft. By matching up the proper shaft diameter, you will be able to reuse the original motor pulley that came on your machine.

Note the following

1: To exclude whether the customer's load is normal, whether it exceeds the actual power of the motor.
2: Whether the power line is thick enough, it must be above line 10.
3: Whether the relay is large enough, at least 60A.

Features

Base RPM: Rotational Speed refers to the motor in rated frequency and rated voltage (or even rated load), the actual speed of the rotor rotation
CW(Clockwise) : Represents clockwise rotation
CCW (Counter-Clockwise): Represents a counter clockwise rotation
ODP (Open Drip-Proof): Air is allowed to circulate in the winding, but the liquid is prevented from falling from the vertical direction to an angle of 15 degrees. Usually used for indoor applications in relatively clean, dry places
Insulation Class F: Including a synthetic resin paint modified with silicone organic compounds for inorganic substances such as mica, asbestos and glass filament,or a synthetic resin, such as alkyd or epoxy with heat resistance meeting this requirement as a binder.The maximum permissible operating temperature is 155 ° C
Pole : Refers to the number of magnetic poles in the excitation winding of the motor.Level 2 means that each phase of the motor contains 2 magnetic poles (one N-pole and another S-pole)

Reference

Frame size - The size of the frame corresponds to the size of the motor. Improper size of motor will lead to motor failure
Phase and voltage - A 230V motor single-phase power supply refers to a 1-Phase 230V AC motor. A 230V motor cannot withstand a voltage lower than 208V. They will run too hot and the motor will fail
RPM - It is very important to match the rpm,the wrong speed will damage your pump. The RPM does not need to be completely matched, and the difference can be close.For example, 3510rpm, 3550rpm and 3450rpm are the same. They all belong to the so-called 3600 RPM motors
