# Quick Answer: How Fast Can Electric Motors Spin?

## What makes an electric motor spin faster?

A faster motor.

One easy way to make the motor run faster is to add another magnet.

As you move the magnet closer to the spinning coil, one of two things will happen.

Either the motor will stop, or it will run faster..

## How do you calculate the speed of an electric motor?

Therefore, for a 60-Hz system, the formula would be:60 x 60 x 2 = 7,200 no-load rpm Ã· number of poles.50 x 60 x 2 = 6,000 no-load rpm Ã· number of poles.A two-pole motor operates at 3,600 rpm (7,200 rpm Ã· 2) unloaded, and approximately 3,450 under load.More items…•

## Does voltage affect motor speed?

Input Voltage: For a fixed load, the speed of the motor is affected by the applied voltage. Increase in voltage = increase in speed. Load Torque: For a fixed voltage, the speed of the motor is inversely affected by the load. Increase in load torque = decrease in speed.

## Can you slow down an AC motor?

Slowing down a single phase AC motor can be complicated and expensive. They are usually built to be run at a certain speed and anything else would be tricking it to do something it wasn’t meant to. Simply slowing it down may cause it to overheat with reduced mechanical self-cooling.

## How fast does a motor spin?

250,000 revolutions per minuteIndustrial motors can spin at a head-spinning 250,000 revolutions per minute.

## How fast can a DC motor spin?

DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.
