The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

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 ...

High power density is an important characteristic in most motors, even in a tiny motor with a high-power-output capability. A high-power-density motor (HPDM) is one that has a high ratio of ...

Electric motors are said to consume nearly 50% of the world's electricity. Industry is focused on replacing inefficient constant-speed drives and motors with microprocessor-driven variable-speed units ...

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 ...
