6. How To Compare Between 8 Hp Single Phase And Three Phase Motor?
8 HP single phase and three phase electric motors are widely used in versatile fields. But there are some differences between their features and performances. A comparative analysis between these two is given below for your convenience.
8 HP single motors require a starting mechanism to produce initial torque. In most cases, these motors use capacitors for this purpose. But 8 HP three phase motors are self-starting. That’s why these motors offer better functionality in advanced electronic applications.
The 8 HP 3 phase motor’s PF rating is more impressive than a single phase motor of the same HP rating. This feature indicates the superior performance of 8 HP three phase electric motors. Usually, 8 HP single phase motors deliver low power factors during operations.
Three phase 8 HP electric motors are compatible with versatile synchronous and asynchronous speeds. Their features are effective for controlling speeds to a large extent. On the contrary, 8 HP single-phase motors have a lower torque speed. Again, their speed control features are not appropriate for high-speed applications.
8 HP 3 phase motors consume electric power more efficiently than a single-phase motor. That’s why it assures you of a low cost while using a three phase motor for your projects. Besides, their amp ratings are perfect for high-density appliances.
Three phase electric motors usually offer superior durability in vulnerable conditions. These motors contain a high-quality structure tolerant to extreme electrical and mechanical pressures.
Besides, 8 HP 3 phase motors are explosion-proof to a certain extent. That’s why their protection class is IP55, which is quite impressive. But single phase 8 HP motors don’t deliver high-class durability as three-phase motors consistently.
Effective Size And Weight
All series of 8 HP 3 phase motors are small in size. Besides, their lightweight is a great advantage for the manufacturer to design complicated devices. These features also make their appearance more lucrative compared to an 8 HP 1 phase electric motor.
8 HP Single phase electric motors of different series require high maintenance to achieve optimum performance. Their maintenance cost is comparatively higher than an 8 HP 3 phase motor.
A three phase electric motor 8 HP is cost-effective because of its outstanding durability and low maintenance cost. On the other hand, 8 HP single phase motor’s cost performance is not impressive like three phase motors.
8 HP 3 phase electric motors are reputable for low noise and vibration while functioning. Their reliable operation ensures effective noise reduction, making these motors preferable to the users. But 8 HP 1 phase motors can’t reduce noise efficiently during their functioning.

12. How To Prevent An 8 Hp Electric Motor Failure?
8 HP electric motors fail due to some technical reasons. You can take preventive measures to increase the longevity of your electric motors. Here, the most common causes and ways of preventing 8 HP motor failure are described.
Overload is caused due to carrying excessive current loads in the different motor windings. If the rated voltage is low, the motors draw excessive current beyond the safety limit. Then, overload occurs.
You can reduce these harmful issues by incorporating an overcurrent-protection feature in your motor. It helps detect overloads.
Overheating is a common cause of electric motor failure. It occurs because of high operating temperatures, low power quality, and low-standard materials. The best way to prevent this issue is to control temperature change properly and use thermal-effective motor materials.
External contaminants, like moisture, dust, etc cause severe damage in 8 HP electric motors. You need to apply proper shielding and place the motor in a clean, dust-free area to prevent contaminations.
Overheating and corrosion often cause degradation of insulating properties of motor windings. It leads to low resistance that is the most challenging problem to overcome. You have to check the motor windings regularly to maintain proper resistance.
