How to calculate power conversion
Thread Content
I would like to ask an expert: I currently have a machine here, with a motor of 2. 2KW, a V-belt connects the two turntables; the turntables are fixed at the top and bottom by bearing housings, and there is a knife on the turntable used for cutting vegetables. I want to ask now: given the current speed and motor power, how can we ultimately calculate the force exerted by the blade on the turntable? How can we convert the motor power into an estimate of the force applied to the vegetables? Please help – give a rough explanation of how to calculate it, along with the calculation process. Thank you! ~~
P = F * S / t. Assuming the force acting on the knife remains constant, the distance from the point of application of this force to the axis is R, and the rotational speed is n revolutions per second, then F = P / (6.28 * R * n). If R = 0.3 meters and n = 30 revolutions per second, then F = 2200 / (6.28 * 0.3 * 30) = 38.9 N
The rotational speed of the motor is N rpm per second. The output torque of the motor, T (KG-CM), is equal to KW X 97400 / N. If the distance from the axis of rotation to the point where the blade exerts force is R (CM), then the force exerted by the blade while cutting food, F (KG), is equal to T / R
