E-2's main propulsion system consists of two DC motors directly driving contra-rotating propellers. An underwater vehicle with a single propeller is subject to undesirable torque forces, especially if ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

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 tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

The purpose of an electric motor is to convert electrical energy to mechanical energy in the form of rotational force. Just about anywhere that machinery is required to create movement, the chances ...
