Servo and stepper motors have similar construction and share the same fundamental operating principle. Both motor types incorporate a rotor with permanent magnets and a stator with coiled windings … and both are operated by energizing or applying a dc voltage to the stator windings, which then causes the rotor to move. However, this is […]

FAQ: Aren’t heat and noise some common stepper motor problems?
Heat and noise both depend on the type of stepper motor, the conditions in which it operates, and what functions the motor serves in the application. Permanent-magnet stepper motors are usually most quiet, as they have a smooth rotor. Hybrid stepper motors are quiet as well. In contrast, variable-reluctance stepper motors are the noisiest type […]
The hybrid servomotor: stepping up to closed loop
by Don Labriola P.E., President, QuickSilver Controls, Inc The use of hybrid servos grows as their control techniques are understood, and the costs of sufficient processing power shrink. Sophisticated control techniques have produced the hybrid servomotor system from the motor style commonly called a hybrid stepper motor when powered by an open-loop step driver. The […]
Tips for Easy Machine Designs
by Hurley Gill, Senior Systems/Application Engineer, Kollmorgen What you need to know about simplifying your machine design approach for optimal servomotor control. An often-asked question from industrial machine builders or integrators is how can they effectively design or implement the conversion of a machine with servo technology to meet performance expectations. This is a specialized […]

How to select an ac motor: A motion engineer’s guide
AC motors are among the simplest of motors amid the common choices for motion control systems. There are a few basic criteria for selecting an AC motor. These involve common variables such as the operating speed and load torque, in addition to the power supply voltage and frequency. First of all, calculate the operating speed. […]
What are Stepper Motors? Technical Summary for Motion Engineers
One of the most common motors used in motion control applications is the stepper motor. These motors are used mostly in positioning applications and have the advantage of being able to be very accurately controlled for the most precise positioning applications, down to fractions of a degree without the use of feedback devices such as […]
What are AC motors? Technical Summary for Motion Engineers
Motors can be classified as either ac (alternating current) or dc (direct current). An ac motor, like any electric motor, converts electrical energy to mechanical energy. AC motors take as their input an ac current, but differ from dc motors in that there is no commutation involved, and can be single or multi-phase. Because ac […]
