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 thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...

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 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 ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

[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 ...

So your electronic hobby skills are coming along quite nicely but you’re not very comfortable doing more than blinking a few LEDs. Now’s a good time to try something new by driving a couple of DC ...

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 ...
