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 ...

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, ...

Motor manufacturers are some of the most useful experts to consult if you need to size motors for a difficult application. Many also provide software to aid in motor sizing. Automation World asked ...

Here’s how power losses and inertia matching affect the efficiency of linear drives. The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common ...

Boosting throughput while maintaining accuracy (or vice versa) is challenging. Most motor-powered motion systems require compliance correction as well Boosting throughput while maintaining accuracy ...

Servo systems may be direct drive or geared. For gearedsystems, the motor selection also involves a choiceof gear ratio. Figure 1 shows a motor connected to aload through an ideal (that is, no ...

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 importance of high torque to meet power-density requirements in robotics. The expanding role of spindle motors. NASA's CADRE robotics program. The three most critical aspects for motors used in ...
