Calculations

The motors have enough torque and speed to do all kinds of experiments and calculations. Measuring the torque of the motor is a challenging task. It requires special expensive equipment. Therefore we suggest calculating it. Efficiency of the motor is calculated as mechanical output power divided by electrical input power: E = P out / P in Get price

Looking for low rpm battery powered motor that runs a LONG

Jun 10, 2013I am looking for a low RPM (4-8 RPM) motor that will run a long time on battery power. For example, any craft store will sell you clock parts that run for over a year on a single AA battery. Sadly, those run at 1RPM if you connect to the sweep second, and there is no torque on that part (plus 1RPM is really slow). PERHAPS I could do something with gearing to slow down a slightly faster RPM Get price

Power consumption when DC motor runs on battery

I have a small dc motor, which is rated for 12V, 3A(rated ). When the motor runs with a load 4000N, the current consumption is 1.5A. So I have to choose a 12V, 3A = 12 * 3= 36W power supply to run the motor.This is because DC power supply can supply continous 3A current without any disturbance. Now I wanted to run same motor on battery. Get price

How I built a quick and easy home

How to Calculate the RPM of a Motor and Speed Reducer

Motors run at a specific revolutions per minute (RPM) and a speed reducer is needed if you want to keep that motor, but have a lower RPM. Calculating the RPM resulting from a motor and speed reducer assembly requires only basic mathematical knowledge. Write down the rated RPM of your motor; for example, 5000 RPM. Get price

Motor and Gear Ratio Guide and Calculator

Motor Types. There are two types of electric motors; standard motors and gear motors. Standard motors have shafts directly attached to the motor windings with shaft output speeds commonly between 1800-3000 RPM. Gear motors have gear reduction transmissions built into them with shaft output speeds commonly between 400-550 RPM. Get price

What speed range can you expect from VFD?

Sep 23, 2004For your application I would run the motor between 40 and 80hz. If need be you could broaden that to 30 to 90 and still have pretty good power. On my machines (mill and lathe, mostly prototype work) I run the motors between 15 and 120 hz., but if I need serious power at slow speeds I put the back gears in. VFD users who run the motors at slow Get price
