If you have a 5 cm radius wheel you would have a torque of 10 Nm (0.05 x 200), with a speed of 400 rpm (5 times greater than the speed of the pedals).
How much torque is needed to move a load?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
How do you calculate torque needed?
The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.
How do you calculate torque needed to rotate wheels?
The required tractive torque of the motor shall be equal to the tractive torque at wheel, Tw = Ft. rw , (i.e. Tractive Torque = Tractive Force x mean wheel radius).

What are the components of load torque?
Components of load torques:
- Friction Torque (TF) The friction torque (TF) is the equivalent value of various friction torques referred to the motor shaft.
- Windage Torque (Tw) When a motor runs, the wind generates a torque opposing the motion . …
- Torque required to do useful mechanical work ( Tm)
How do gears increase torque?
The rotary machine’s output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses. While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque.
How much torque does a 1 hp motor have?
The 1800 RPM, 1HP motor produces 3 ft. lbs of torque at 1800 RPM. The 3600 RPM, 1HP motor produces 1.5 ft.
What is the holding torque?
A stepper motor’s holding torque is the amount of torque needed in order to move the motor one full step when the windings are energized but the rotor is stationary. Stepper motors can hold a load against an external force when the motor is stationary. …
How can I increase my bike torque?
5 Simple Ways to Increase Bike Power
- Ride in bigger gears. Riding in bigger gears at the same cadence in a particular set of conditions makes for a consistently higher power output. …
- Ride uphill. …
- Ride into headwinds. …
- Use block training. …
- Follow the 75-percent rule.
Does more torque mean faster acceleration?
A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … Higher torque doesn’t mean one vehicle will necessarily be faster than another, though. For example, a Ford F-250 makes 925 lb-ft of torque, while a Honda S2000 has just 162 lb-ft.
What torque means in bikes?
Mathematically, torque is defined as the cross product of the lever-arm distance and force, which tends to produce rotation. In the automotive world (or bike world in your case), torque is the force which gets your bike moving. The more torque, the quicker the bike can move.
How much torque does a car need?
The lug nuts that attach the wheels to your car typically need to be tightened to about 100lb. -ft of torque — meaning the operator must apply 100 pounds of force to the end of a foot-long wrench.
