Converting electricity into mechanical energy is the job of the industrial electric motor. Motors create either a linear or rotary force. While electric motors can be powered by direct current (DC) sources like batteries, they are more often powered by alternating current (AC) sources like generators or the power grid. Here's an overview of the main components of industrial electric motors.
In industrial applications, the type of magnet you choose has major implications on motor design, project costs and overall performance. It’s important to make an informed decision in this step of the process. But where do you start? How do you know what type of magnet to use?
One exciting recent development in motor science is the rise of the linear motor. Linear motors are electric induction motors that use some very interesting principles. They make possible ultra-fast “maglev” (magnetic levitation) trains and other innovations.
Any motion control expert should understand the difference between brushed and brushless DC motors. Brushed motors were once very common. Though they’ve been largely supplanted by their brushless counterparts, the right DC motor of either type can make a project far more efficient.
Motion control is the engineering discipline focused on moving a load from one place to another. It does this by precisely controlling the position, velocity, and acceleration of the load under defined operating conditions.
Stepper motors have been developed to deliver excellent precision, allowing very predictable performance when the step angle and gearbox ratio are both known. As a result, stepper motors have naturally become the motor of choice for many new electronics. But even with the great visibility into position and velocity that a stepper motor offers, some engineers have taken things a step further.
