The new RE 65 power package delivers 250 watts and can cope with the toughest demands. The motor is particularly suitable for applications where high efficiency, high power density and a minimal ...

Oversizing often happens when engineers try to match the inertia between the load and the motor rotor, so that they can tune the drive’s velocity, torque or position loop relatively tightly to meet ...

Size plays a key role in miniaturization and automation, where smaller is usually better. Conventional electromagnetic motors have certain restrictions when it comes to reducing dimensions while ...

The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...

One of the challenges that face motion-control engineers is how to properly select a motor. If the motor is undersized or too small, it will not handle load. If the motor is oversized or too large, ...

Some carefully selected analogies might make the reasons for this clearer. Is it easier or harder to control the speed of a motor cycle or a heavily loaded truck? Most people would correctly surmise ...

The smart motor control module—MMP757188-36 in this example—validates the results. Figure 2 The MMP757188-36 is a motor control module for smart motor applications. Source: Monolithic Power Systems ...

The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common linear actuators — linear induction motors, rolled and ground ball screws, and rack ...

1. Don't fear servos. There are many different levels of positioning and motor controls now. Some basic variable frequency drives can even be used to do what could have been done only with coordinated ...
