  • 4 Easy Ways to Determine Gear Ratio (with Pictures)

    Oct 16, 2019· The power needed to drive the load is geared up or down from the motor by the gear ratio. The motor must be sized to provide the power needed by the load after the gear ratio is taken in to consideration. A geared up system (where load RPM is greater than motor RPM) will require a motor that delivers optimal power at lower rotational speeds.

  • How to Calculate Power Based on Force and Speed dummies

    In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object's speed, v, .

  • Understanding Variable Speed Drives (Part 1) | Electrical ...

    While all variable frequency drives (VFDs) control the speed of an AC induction motor by varying the motor's supplied voltage and frequency of power, they all do not use the same designs in doing so. There are three major VFD designs commonly used today: pulse width modulation (PWM), current source inverter (CSI), and voltage source inverter (VSI).

    Apr 25, 2017· Benefits. There is a tradeoff between speed and torque, which is rotational power. When the gear ratio is 1:1, the amount of torque is the same, and the speed is the same. However, as soon as you increase the gear ratio (1:4, for example), you're going to cut the amount of torque but significantly increase the amount of speed.
