Small Motor Articles

Electric motors drive industrial machinery and an array of devices throughout the world. The two main sources of power, alternating current (AC) and direct current (DC), are complemented by two types of electric motors that differ in operation and application. Engineers, technicians, and operators must understand the key differences between AC and DC motors to…

A brushless direct current motor (BLDC) is a small but powerful type of electric motor that uses direct current as its power source. Because of their size and efficiency, BLDCs are increasing in their popularity and the number of applications they’re used for. What is DC Power? Electrical current is the movement of electrons through…
