A choke is a passive device that adds inductance to a circuit. Inductance is a property of a coil of wire that resists any change to the current flowing through it. (Straight wires also possess a small amount of inductance.) In other words, if current through the coil increases, the magnetic field of the coil […]
What is a constant voltage drive for a stepper motor and when is it used?
There are two fundamental types of stepper motor drives: constant voltage drives, which supply a fixed voltage to the motor, and constant current drives, which manipulate voltage to ensure that a constant current is delivered to the motor. Stepper motor electrical basics The most fundamental equation governing the behavior of a stepper motor is Ohm’s law, […]

The intralogistics industry is a fastest-growing market — and one motion-component supplier aims to address the industry’s unique needs. “Three of the world’s top five material-handling suppliers use NORD drive technology, and we have long-term supply agreements with two of the suppliers,” says NORD Gear Corp. president and CEO Torsten Schultz One solution for intralogistics […]
John Uzzolino joins maxon Group to head up Parvalux product line in U.S.
maxon Group of Taunton, MA has hired John Uzzolino to head up the business development activities for the Parvalux product line in the United States. In December, maxon Group acquired the British geared motor manufacturer Parvalux Electric Motor, Ltd. The acquisition expands the maxon portfolio with dc drives in the power range of up to […]
What is a motion profile?
Servo applications require defined, controlled movements, often to move a part to a specified position at a precise velocity or along a predetermined path. A motion profile provides the physical motion information and graphically depicts how the motor should behave during the movement (often in terms of position, velocity, and acceleration) and is used by […]

What are some connectivity options for smart motors?
The class of motors known as “smart” motors continue to see a steady increase in use in many industrial applications. A smart motor is essentially a motor that integrates a number of other components together into one physical unit. Common configurations include a motor and drive, but can also consist of integrated encoders and controllers […]
