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, […]
New compact remote drives from B&R for modular machines
Two new compact motor-mounted drives from B&R are additions to the ACOPOS motor series and will aid development of modular plants and machinery by reducing installation costs and saving cabinet space. The new devices cover a power range up to 0.35 kW, and the smallest version measures just 60 mm wide by 90 mm high. […]
Commander drives from Control Techniques now with free five-year warranty
Purchasers of Commander drives will now be able to register to extend the products’ warranty from two years to five, at no extra cost. The new offer relates to the Commander C200 and C300 – general purpose drives designed for ease of setup and installation. The firm states the move to extend the warranty from […]
New control functions for model-based control servo drive from B&R
B&R has extended its model-based control for the ACOPOS P3 servo drive to include three new control functions. The functions are integrated into B&R’s Automation Studio engineering environment and allow the controller to be adjusted more precisely. This way, machine productivity and speed can be increased. Vibrations and oscillations decrease, so that machine components are […]
New microprocessor-based digital dc drives from AutomationDirect
The IronHorse GSD8 series of dc drives is a microprocessor-based design with non-volatile memory storage that is programmable with adjustable parameters, programmable alarm outputs and offers a digital closed-loop algorithm for motor control. GSD8 output power available is 1/2 to 1 hp at 120 Vac input and 1 to 2 hp at 240 Vac input; […]
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 […]
Motion technologies and software for next-generation eBikes
Since their emergence in the early 1990s, eBikes have undergone a steady series of improvements in range, reliability, and performance that have won them a growing number of loyal users worldwide. Equipped with specially engineered frames, high-capacity Li-Ion batteries, and highly efficient drive control electronics, today’s eBikes have become a low-carbon option to cars for […]
