Can you use a DC 7.2V 400mA transformer to power a small motor?

First, there are no DC Transformers, transformers work on AC. If you have an AC/DC wall converter that has an output of 7.2 v DC, and a max current load of 400mA, then you can use this to power a DC motor that requires less than (7.2 x .4 = ) 2.88 watts of energy.

Why no load current in transformer small?
No load current is energizing current. This is effectively "lost" power, power used in the transformer to energize the core. It, therefore, should be small!
How do you find the maximum amp draw on a step up transformer?
It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.
What combination of medals work best to power a small motor?
Gold Medal winners in rowing or triathlon would probably be the best to power a small motor..
100 amps mccb trip when charged it is connected to small power transformer?
what is the fault in the transformer, it trips when it is charged.it is charged through the 100 amps MCCB.
Applications of hysteresis motor?
it is used for small power application ...
What is the difference between transformer and generator and motor?
A motor is a machine that converts other forms of energy into mechanical energy, therefore creating motion. A generator converts mechanical energy into electrical energy via the method of magnetic induction. You should probably check up Michael Faraday and Lenz. Or maybe look in a HSC Year 12 text book like Jacaranda.
What is meant by the optimal design of power transformer?
It depends on the purpose - do you want the transformer to be low loss? As small as possible? to be able to withstand large power surges? as quiet as possible? To be able to operate for a wider than normal range of frequencies?Power transformer design is a very big topic. Many engineers spend their entire careers dedicated to optimizing transformers for specific purposes.
How does the alternator recharge the battery?
An alternator is just a small generator that generates AC power and is converted to 12v DC power via a transformer for battery storage and use.
What methods can you use to power and control a small electric motor using an Arduino without directly drawing power from the Arduino?
Have the Arduino control a relay that connects an external power source to the motor.
How do you convert 110v to 5v?
Depending on the application and other factors, it will TYPICALLY be best to use a transformer. If it's a low current application, you can purchase a small 5V power supply transformer for under $20.00, US.
What is percentage of transformer loss at no load condition?
major component of power loss in a transformer is secondary resistance.when transformer is operated under no load,no current flows through the secondary.so under no load conditions transformer has just very small megnetic losses.
How can install power transformer?
If you are referring to 'power transformers' used in transmission systems, then the requirements are far too complicated to be answered in this forum. If, on the other hand, you are referring to a 'power transformer' in the sense of a small transformer used to reduce your mains or supply voltage at home, then the volt ampere rating of the transformer must equal or exceed the load requirement. The primary and secondary voltages must match the primary supply voltage and the voltage requirement for the load. Any requirements for earthing (grounding) must be observed.
