Webb17 sep. 2014 · An AC drive not only can control operating speed, but it can also reduce motor acceleration and deceleration rates. VFDs can reduce inrush currents and thus starting torque by 30-75% compared to across-the-line starters. This reduces wear on belts, gears, chains, clutches, shafts and bearings.

The other motor is an expensive military spec model, similar in specs to the Pololu motor, 12 volts, more torque, planetary gearbox (for quietness) and a gear ratio of 29:1. WebbThey can make the motor speed up, slow down, stop, or even go backwards at any time. They accomplish this by controlling and directing the flow of electricity through the motor's wires. Without a servo drive, a motor might just spin uncontrollably or not spin at all. Some servo drives control small motors, like in the elbow joint of a robot arm. bird box movie download in hindi
