Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...

The precise meaning of the term ‘servo’ in the context of motors and drives is difficult to pin down. Broadly speaking, if a drive incorporates ‘servo’ in its description, the implication is that it ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and position-control loop are also essential.

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...

Classic radial gap, stacked lamination stators. (Shown with and without windings.) As we look at catalogs of electric motors, we find them classified by power, speed, and torque. To a large extent, ...

With a Plug & Drive PD2-N integrated closed loop stepping motor, Nanotec expanded its offering of integrated stepper motors with closed loop sine commutation. Nanotec is expanding NEMA 17 applications ...

One of the more critical decisions engineers can make when designing any type of motion control process is choosing the motor. Getting the right motor, both in terms of type and size, is imperative to ...

Combining a high-torque step motor with an on-board drive, encoder, controller and closed-loop servo software into a single package, the integrated motors save on space, wiring, and cost over ...
