# Can DC motor generate power

Contents

Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive.

## How many volts can a DC motor generate?

Typical DC motors may operate on as few as 1.5 Volts or up to 100 Volts or more. Roboticists often use motors that operate on 6, 12, or 24 volts because most robots are battery powered, and batteries are typically available with these values.

## How much electricity can a 12v DC motor generate?

That is a beast of a motor. It can produce over 1300 Watts which is 91 amps at 14.7 Volts – more than enough to charge anything, including car batteries.

## Can a DC motor run on AC power?

The AC series motor you describe is a universal motor, and will work fine on DC. The speed characteristics will be a little different, since when running on AC there’s a significant reactive drop in the field windings that reduces the available driving emf.

## Can a small DC motor generate electricity?

Both brushed and brushless DC motors can be operated as generators.

## 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 many watts does a DC motor use?

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.

## What is the rpm required to generate electricity?

1,000-1,800 rpm is the rotational speed required by most generators to produce electricity. The high-speed shaft drives the generator which produces AC electrical current.

## How many amps does a 12V motor use?

For example, a tiny 12 Volt motor might consume 1 Amp and the motor would produce 12 x 1 = 12 Watts of power (about 0.016 HP). Similarly, a 775 Volt motor might consume 2 Amps and produce 775 x 2 = 1550 Watts of power (about 2.08 HP).

## Which is more efficient AC or DC motor?

Consequently, AC motors are less efficient than DC motors. In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings.

## Why starters are required in a DC motor?

Starters are used to protect DC motors from damage that can be caused by very high current and torque during startup. They do this by providing external resistance to the motor, which is connected in series to the motor’s armature winding and restricts the current to an acceptable level.

## What happens when we give DC supply to AC motor?

(2) The other effect of the DC supply on the AC motor is that if we give DC supply on the AC motor then the windings of the AC motor may be burn because when the one reason is AC windings always have less resistance than DC windings and the other reason is when we give DC supply on the AC motor there are no Self- …

## Can a DC motor charge a battery?

Of course you can charge a battery from a dc motor, that’s how generators work. You just can’t do it at the same time you’re powering the motor.

## Is DC generator and DC motor same?

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. … DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
