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 |

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

**How to Calculate DC Motor Amperage**

- Look on the label of the DC motor. Write down the voltage and the wattage on a sheet of paper. …
- Enter the wattage into a calculator. Press the “Divide” button and then enter the voltage you wrote down.
- 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.
