*How To Calculates the torque, speed as well as Power of electrical motor as well as the relationship**Do yous know what is The formula to calculates the torque, speed as well as Power of electrical motor as well as its relationship?*

The formulas as well as how to calculate Torque, Speed (Rpm) as well as Power of Electric motor, as well as what is the human relationship betwixt Torque, Speed and Power.

We tin orbit the sack run across the Specifications on the Name Plate of an Electric-motor, which lists about information almost the Electric Motor, including the Torque, Speed (Rpm) as well as Power (KW or HP).

How attain yous know the value of Torque, Speed and Power on an Electric motor, as well as what is the human relationship betwixt Torque, Speed and power?

An electrical motor is a device that tin orbit the sack convert electrical liberate energy into displace liberate energy (rotate), as well as this is sure enough influenced yesteryear three factors, namely the electrical ability used, how fast the rotation is produced, as well as how much ability (torque).

**The formula to calculates Speed of Electric Motor**

The rotation speed produced yesteryear an Electric Motor is also influenced yesteryear several factors, namely: Frequency as well as Number of Poles.

The normal speed of rotation (Rpm) is also written amongst the missive of the alphabet N, as well as Speed is determined yesteryear how much Power is used multiplied yesteryear the angle of stage (120⁰) divided yesteryear the position out of poles.

N = (f x 120) : P

- N : Rotation/Speed (Rpm)
- f : Frequency (Hz)
- P : Number of poles (Pole)

**For example**, Three Phase Motor, operated at frequency 50Hz, as well as the position out of poles are four poles, as well as thus the Speed (Rpm) of Motor is:

N = (f x 120) : P

- N = (60Hz x 120): 4
- N = 7200: 4
- N = 1800Rpm.

## How To Calculates the torque, speed as well as Power of electrical motor as well as the relationship

Calculates Of Torque, Speed & Power |

Calculate the Torque, Speed and Power of motor

Motion Power produced from an electrical motor is called Torque (Torque) inwards Nm (Newton-meter) units.

In general, nosotros tin orbit the sack abide by out the human relationship betwixt Speed, Torque as well as Power, namely:

If nosotros need an electrical motor that has a stronger torque, as well as thus commonly nosotros volition pick out an electrical motor amongst a large power, also that the rotation speed of the electrical motor also affects the size of the torque, Higher Speed = Smaller torque.

**A. Relationship betwixt Power as well as Torque of electrical motor (directly proportional)**

- Higher Power of motor, as well as thus Higher Torque
- Lower Power of motor, as well as thus Lower Torque

**B. Relationship betwixt Speed (Rpm) as well as Torque of electrical motor (inversely proportional)**

- Higher Speed of motor, as well as thus Lower Torque
- Lower Speed of motor, then Higher Torque

The enquiry is, is the statements higher upwards right?, for to a greater extent than details almost how the Relationship betwixt Speed, Torque as well as Power actually is, as well as thus nosotros tin orbit the sack run across it from the formulas as well as about examples of calculations below:

**The formula to calculates Torque, Speed and Power**

P = (T x N): 5252

T = (5252 x P): N

N = (5252 x P): T

- P: Power inwards HP (Horse Power)
- T: Torque (Nm)
- N: Speed (RPM)
- 5252 is the value of conclusion (Constant) for motor ability inwards units of HP

**Example calculation:**An Electric Motor has a Power is

**100 HP**, amongst speed is

**1800 Rpm**, as well as thus the Torque is:

T = (5252 x P) : N

- T = (5252 x 100HP) : 1800Rpm
- T = 525200 : 1800
- T =
**291,7 Nm**

*Is it truthful that Higher Power of motor, as well as thus Higher Torque?*

*Example calculation:*An Electric Motor has a Power of

**200 HP**, with speed of

**1800 Rpm**, as well as thus the Torque is:

T = (5252 x P) : N

- T = (5252 x 200HP): 1800Rpm
- T = 1050400 : 1800
- T =
**583,5 Nm**

**, when an electro motor has Power**

*"Directly proportional"***100 HP**, the torque is

**291,7 Nm**, piece Power of motor is enlarged to

**200 HP**, the Torque

**583,5 Nm**.

*Furthermore, is it truthful that Higher Speed of motor, as well as thus Lower Torque?*

*Example calculation:*An Electro Motor has a Power

**200 HP**, amongst speed

**3600 Rpm**, as well as thus the Torque is:

T = (5252 x P) : N

- T = (5252 x 200HP): 3600Rpm
- T = 1050400: 3600
- T =
**291,7 Nm**

**, when the Speed of motor is**

*inversely proportional***1800 Rpm**, the Torque is

**583.5 Nm**, piece the speed of motor is

**3600 Rpm**, as well as thus the torque is

**291.7 Nm.**(

**Power of Motor are same 200 HP**"Thanks a lot for visiting on our KlikPengetahuan.web.id Blog. Let me know if the link is broken or is not working very well"
