# How many amps does a 12 volt DC motor draw?

Contents

At this point it is drawing the maximum amount of current and applying maximum torque. A low voltage (e.g., 12 Volt or less) DC motor may draw from 100 mA to several amperes at stall, depending on its design.

## How many amps does a 12v DC motor use?

0.5 HP = 42 amperes.

## How many amps does a DC motor draw?

Full load amps in 120 and 240 volts DC motors

Motor Rating (hp) Current (amps)
120 V 240 V
1 9.5 4.7
1 1/2 13.2 6.6
2 17 8.5

## How do you determine the amperage of a DC motor?

How to Calculate DC Motor Amperage

1. Look on the label of the DC motor. Write down the voltage and the wattage on a sheet of paper. …
2. Enter the wattage into a calculator. Press the “Divide” button and then enter the voltage you wrote down.
3. Press the “Equal” button. The result displayed is the DC motor’s amperes.

## Can I connect DC motor directly to battery?

Yes. No need for voltage regulator or similar. Voltage would be ~24V minus some voltage drop on transistors on H-bridge, so it is safe for motor, because this is the voltage the motor is rated for.

## How do you calculate the power of a 12V DC motor?

If the DC motor is 12 v and has 3 amps, then is 36watts and a 12 volt battery on 75 amps/h will give you 12*75=900watts/36 = 25 hours.

## What are the 3 types of DC motors?

There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.

## What is the torque of 12V DC motor?

Package Includes:

Model No. N20-12-100
Rated Speed (RPM) 100
Operating Voltage (VDC) 6 ~ 12
Rated Torque(kg-cm) 0.52
Stall Torque(Kg-Cm) 1.8

## Which battery is best for DC motor?

7.2V: six AA or AAA rechargeable NiMh batteries is perfect for 7.2V DC gear motors. These are usually in a battery pack rather than as individual cells and you will need a more specific NiMh battery pack charger. 7.4V: two LiPo cells can often power a microcontroller and works great for 7.2V DC gear motors.

## How much current does a 3v DC motor draw?

Approximate specifications at 3 V: free-run speed of 20,000 RPM, free-run current of 350 mA, stall current of 4 A, stall torque of 55 gf-cm (0.75 oz-in).

## How do I know what AMP my motor is?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.

## How many amps does my motor draw?

Calculate the amps used by dividing the wattage by the voltage. For example a 500-watt motor — running on 50 volts — will draw 10 amps. A motor with the same wattage — running on 20 volts — will use 25 amps. This is the theoretical number of amps used by the motor.
