Electric Motor and Gas Engine Horsepower Equivalency - Physics …
2010年7月18日 · The main difference between electric motor horsepower and gas engine horsepower is the way they generate power. An electric motor uses electricity to create rotational motion, whereas a gas engine uses combustion to create energy. This results in differences in efficiency, torque, and power delivery between the two types of motors.
Calculating the required motor size to move a load. - Physics Forums

Torque calculation of a motor with permanent magnets - Physics …
2021年12月27日 · The formula for calculating torque in a motor with permanent magnets is T = B x L x N, where T is torque, B is the strength of the magnetic field, L is the distance between the center of the rotor and stator, and N is the number of turns in the coil. 3. How do permanent magnets affect the torque of a motor? Permanent magnets play a crucial role ...
Calculating the torque required in an electric bicycle - Physics …
2013年3月8日 · Yes, the torque of an electric bicycle can be increased by either using a motor with a higher torque rating or by changing the gear ratio. A higher torque motor will be able to provide more power and a lower gear ratio will allow the motor to turn more efficiently, resulting in increased torque. 5. How does the terrain affect the torque ...
Calculating Generator Shaft Torque - Physics Forums
2010年8月11日 · The equation for calculating torque is Torque = Power x 60 / (2 x PI x Rot), and there is a direct correlation between motor torque and generator torque. The question remains whether or not the 2.2kW motor with an 18:1 gear reduction will be able to supply the required torque for the generator. The output torque will be greatly increased with the
How do I calculate the minimum torque needed for a grinder motor
2012年7月20日 · The minimum torque needed for a grinder motor can be calculated by considering the speed and power requirements of the grinder. The formula for torque is torque = power / (2 x pi x speed). By knowing the power and speed requirements of the grinder, you can plug them into this formula to determine the minimum torque needed.
Torque calculations for logging winch - Physics Forums
2012年2月3日 · force = torque / distance. In this case, the distance will be the radius of the sprocket or: F = T / r. After calculating chain tension, convert back to torque in the axis of the 10" sprocket. T = r X F. You will need to convert from torque to tension and back twice (once for each speed reduction stage).
Torque calculations for a small electric vehicle - Physics Forums
2020年3月31日 · 31. 2. Torque on each driven wheel will be determined by the resulting force pulling the car back in alignment with the road divided by 2, or less, if you wish to introduce a safety factor due to such things like uneven traction, …
Pulley Torque Calculations for Motor with Added Pulley: Is the …
2011年10月18日 · You have a socket set with 2 bars, one 1.0 m long and one 0.5 m long. To apply the same torque to the bolt, the 1.0 m bar requires 100 N applied to the end. The 0.5 m bar requires 200 N applied. In your example, the torque applied by your motor to a small shaft or a large pulley will be the same. 1450 Nm.
Electric motor - variable torque vs speed - Physics Forums
2024年8月22日 · The 400rpm is to indicate that the speed at low load should be much faster than with high load. If it's 200 or 600 rpm doesn't really matter, and the 10Nm is what I'd guess a 500w motor could be able to pull at 400rpm. Winch will be used many times a day, every day for some weeks when I'm doing some project with heavy lifting.
