In summary: However, there are some factors that can affect the maximum speed. At the lowest point, the motor needs to turn more RPM in order to lift due to the mechanical advantage of the horizontal lead screw distance to vertical distance lift. This means that for a given rotation of the motor, the vertical distance lifted is greater at the lowest point compared to the highest point. On the other hand, at the highest point, the motor only needs to turn a lower RPM to lift vertically due to the mechanical advantage of the horizontal movement causing a larger vertical movement. This can lead to confusion about where the maximum speed should be calculated. In conclusion, the maximum speed for a scissor lift is typically calculated at the lowest point, where the motor needs to turn the

may someone teach me how to calculated the maximum speed from my case scissor lift? is it when at lowest point or highest point? I need your help..i can't get the equation...i got some confuse, due to at lowest point, the motor need to turn more rpm in order to lift due to mechanical advantage..horizontal lead screw distance to vertical distance lift...Beside that, at higher point the motor only need to turn lower rpm to lift vertical..due to mecHAnical advantage..the little move of horizontal will cause vertical move a lot..But in another way round, the speed should be max in lowest load which is at highest point position..but the calculation show we need highest rpm in lowest point..Why? May you teach me the correct way in calculate the maximum speed needed in my case for choosing a motor..
Thanks..

The equation for calculating the maximum speed of a scissor lift is:Vmax = 2π * R * Nwhere Vmax is the maximum speed, R is the radius of the lifting arm, and N is the number of rotations per minute (RPM) of the motor. For example, if the radius of the lifting arm is 1 meter and the RPM of the motor is 2000, then the maximum speed of the scissor lift is:Vmax = 2π * 1m * 2000 RPM = 12,566 m/s
 

What is speed?

Speed is defined as the rate at which an object moves, usually measured in distance per unit time.

How is speed calculated?

Speed is calculated by dividing the distance traveled by the time it took to travel that distance. The formula for speed is: speed = distance / time.

What units are used to measure speed?

Speed can be measured in various units, such as meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s).

Can speed change?

Yes, speed can change if the distance or time changes. An object can accelerate or decelerate, causing its speed to increase or decrease.

What is the difference between speed and velocity?

Speed and velocity are often used interchangeably, but they have different meanings. Speed is the rate of motion, while velocity is the rate of motion in a specific direction. In other words, velocity takes into account both speed and direction.
