If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed ...

The precise meaning of the term ‘servo’ in the context of motors and drives is difficult to pin down. Broadly speaking, if a drive incorporates ‘servo’ in its description, the implication is that it ...

Specifics about high-power-density motors (HPDMs). Applications best served with HPDMs. Why BLDCs are perhaps the most preferred among HPDM architectures. High power density is an important ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

The Raspberry Pi Pico is a low-cost, high-performance microcontroller board, It has flexible digital interfaces and it is very small but powerful. The board offers users the chance to develop projects ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between ...

[Afroninja] is back with another great tutorial on basic electronics. This time around he’s explaining H-Bridge motor controllers and how they work! Even if you don’t have much (or any) experience ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
