# How much weight can a 12v DC motor lift?

Contents

The maximum torque is given as 1.2 kg*cm (which includes the gearbox-transition), which means having wheels with an radius of 1 cm (or 2cm in diameter) will give you a force that is equivalent to 1.2 kg in weight at nominal voltage, as long as your electronics can provide a current of 300 mA (load current).

## How strong is a 12v DC motor?

12v DC motor with maximum 1.5A capacity can generate 18W of power. 12v DC motor with maximum 3A capacity can generate 36W of power.

## How much weight can my motor lift?

No motor by itself can lift any weight. You need to have a winch with a gear reduction. The weight depends on the rating of the winch, the gear ratio, and the size of the motor.

## How much load can a motor take?

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.

## 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 is the torque of 12V DC motor?

Product Specification

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

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 much weight can a 1 hp motor lift?

The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.

## How much weight can a 2 hp motor lift?

To find the weight each opener can lift simply divide 550 lbs by the manufacturer HP rating and then multiply by (2/3). For example, a 1/2 horsepower garage door opener should be able to lift 275 pounds while a 1 HP opener can lift 550 pounds.

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

In our example input electrical power of the motor is 0.22 A x 6 V = 1.32 W, output mechanical power is 1000 rpm x 2 x 3.14 x 0.00126 N•m /60 = 0.132 W. Motor torque changes with the speed. At no load you have maximum speed and zero torque.

## What is the efficiency of a DC motor?

The value of the efficiency of a DC motor could typically be in the range of 70 to 85%. Larger the machine higher will be the efficiency. Losses consist of Armature and field copper losses, core loss, friction and windage loss.

## How do you calculate motor load?

It is combination from Amperage and Voltage value. Basic formula for Power is P (watt) =I(ampere) x V (volt). Power also measured in Horsepower (hp) unit. For common conversion from electrical Horsepower to Watt is 1hp = 746 watt.

## How much power does a 12v motor use?

12v DC motor with maximum 1.5A capacity can generate 18W of power. 12v DC motor with maximum 3A capacity can generate 36W of power.

## How long can a 12v DC motor run continuously?

You should anticipate, given proper attendance, that the motor can run continuously for the life of its brushes, which should be in the range of six months to a year. Presuming that the motor is too small to have its brushes changed by a trained electrician while running.

## How many amps does a DC motor need?

Full load amps in 120 and 240 volts electrical DC motors.

Motor Rating (hp) Current (amps)
120 V 240 V
2 17 8.5
3 25 12.2
5 40 20
