Using Current Regulation in DC Motor Drivers |Article | MPS
How to use the current regulation feature available with motor drivers, such as MPS''s MP6522, to regulate and control the large currents that flow when starting a DC motor. By understanding how to properly limit a motor''s start-up current, designers are able to not only use smaller motor drivers, but also optimize their system''s current delivery.

How do electric motors work?
There are two ways to overcome this problem. One is to use a kind of electric current that periodically reverses direction, which is known as an alternating current (AC). In the kind of small, battery …
Build a Simple Electric Motor! | Science Project
An electric motor uses the attracting and repelling properties of magnets to create motion. An electric motor contains two magnets; in this science project, you will use a permanent magnet (also called a fixed or static magnet) and a temporary magnet. The temporary magnet is also called an electromagnet.A permanent magnet is surrounded by a …

Selecting Small DC Motors for Low-power Applications
This type of motor can be connected directly to a battery, which makes it ideal for battery-powered tools. It is exceptionally efficient and relatively inexpensive. Unfortunately, the major drawbacks of a brush-type motor include limited service life (typically 1,000 to 5,000 hours) and limited speed (typically below 10,000 rpm), which are ...
Phase current VS Battery current...
the battery current will hit the 100% (200A) in the right circumstances ( maybe not in this extreme case of phase 20% and battery 100%), its just that due to the very low phase current setting ( limiting ) its also holding back the battery current as the controller will not have the torque to get you up to your maximum speed.

Tips for Powering Motors with Batteries
To calculate how long a battery will last, we need two figures; the battery''s capacity and how much current will be drawn by the motor. Batteries measure their capacity in milliamp hours, mAh. This states how many hours the battery can supply 1 mA of current, or how many mA of current it can supply for one hour.
