Title: Analysis of the conversion formula between 3.5 horsepower kW and kWh in three-phase motors
I. Introduction
In modern industry and daily life, the conversion of motor power is a common requirement. Especially in three-phase motors, the conversion between power units such as horsepower (hp), kilowatts (kW) and kilowatt-hours (kWh) is particularly important. This article will focus on the conversion formula of 3.5 horsepower kilowatts (hpkakw) and kilowatt hours (kWh) in three-phase motors to help readers better understand and apply.Frankenstein
2. What is the unit of power in a three-phase motor?
1. Horsepower (hp): It is a unit of power that is often used to describe the working capacity of mechanical equipment.
2. Kilowatt (kW): In the International System of Units, kilowatt is the unit of power and is often used to express electrical power.
3. Kilowatt-hours (kWh): is a unit of electrical energy, which indicates the amount of electrical energy consumed by a device over a period of time.
3. The conversion relationship between hp and kW in three-phase motors
In three-phase motors, the SI system of units is usually used, so it is necessary to convert horsepower to kilowatts for uniform calculations. The conversion formula is generally as follows:
kW = hp×0.7457 (where hp is the number of horsepower)
Therefore, for a 3.5 hp motor, its power (kW) can be calculated by the above formula.
Fourth, the conversion relationship between kW and kWh and the operation characteristics of three-phase motor
Relationship between 1.kW and kWh: Kilowatt is a unit of power, while kWh is a unit of electrical energy. Multiply the power of a device by the operating time to get the amount of electricity it consumes. That is: electrical energy (kWh) = power (kW) × time (h).
2. Operation characteristics of three-phase motor: Three-phase motor has the characteristics of high efficiency, stability and easy control, and is widely used in industrial fields. Its power is different from that of a single-phase motor, so the characteristics of a three-phase motor need to be considered in the conversion formula.

Based on the previous introduction, we can derive the power (kW) conversion formula for a 3.5hp three-phase motor. First, 3.5hp is converted to kW and then multiplied by the running time to get electrical energy (kWh). The specific formula is:
kW=3.5×0.7457
Electrical Energy (kWh) = Power (kW) × Time (h)
Through this formula, we can conveniently calculate the electrical energy consumption of the 3.5hp three-phase motor during operation.
VI. Conclusions
This paper introduces the relationship between power units such as horsepower, kilowatt and kilowatt-hour in three-phase motors, and focuses on the kW and kWh conversion formula of 3.5hp three-phase motors. By understanding these conversion relationships, it is possible to better understand the performance of the motor and its electrical energy consumption during operation, which provides convenience for industrial production and daily life. Hopefully, this article will be helpful to readers.
