Piezo actuators and motors are often the preferred technology when an application requires movements of a few millimeters or less with high resolution. And while these small-scale applications don’t typically attract the same level of attention as those that require massive 100 mm diameter ball screws or enormous 12-meter gantries, applications in the single- and […]
New high force voice coil motors from Moticont
Moticont has added a new, higher continuous force, higher peak force linear voice coil motor to its series of 2.750 in. (69.9 mm) diameter x 3.50 in. (88.9 mm) long (housing) voice coil motors. The LVCM-070-089-03 linear voice coil motor features 40.86 lb (181.5 N) continuous force and 129.1 lb (573.4 N) peak force. This […]
35-mm CBL35C programmable electric moving-coil servo actuator from SMAC Corp.
Now a 35-mm-diameter SMAC Corp. CBL35C electric cylinder has a built-in controller. The latter lets the CBL35C control force, position, and velocity — and facilitates simple installation. The actuator works for applications with limited space but needing accurate control … Plus the CBL35C provides significantly longer life, programmability, high speed, accuracy, and energy efficiency maintaining […]
What are linear ultrasonic piezo motors?
Ultrasonic piezo motors create useful rotary or linear motion by exciting a piezo element to produce high-frequency oscillations. In linear ultrasonic piezo motors, the piezo element is a piezoelectric plate. Applying voltage excites the plate at its resonance frequency and creates eigenmode oscillations – meaning all parts of the plate move sinusoidally at the same […]
H2W develops highest force voice-coil actuator
H2W Technologies has developed what it says is the world’s highest force commercially available non-commutated DC linear actuator, otherwise known as a direct drive voice coil actuator. The model NCC08-75-3000-3X is capable of generating a continuous force of 300 lb (1,330 N) and a peak force of 900 lb (4,000 N) at a duty cycle […]
PI releases new catalog of piezo-mechanic nanopositioning motion systems
PI (Physik Instrumente) has released a new 250-page catalog on precision mechatronic actuators and nanopositioning systems based on piezo drive technology and frictionless flexure guiding systems. Products covered in this catalog use PI’s in-house designed and manufactured Mars Rover-tested piezo ceramic actuators as their drive principle. A special form of electro-ceramics, piezo actuators deliver a […]
What is a hollow core linear voice coil motor?
A linear voice coil motor (also referred to as a “voice coil actuator” or “linear DC motor”) is a simple yet very precise type of electric motor, consisting of just two primary parts – a coil and a magnet. When current is applied to the coil, a force is generated. The magnitude of the force […]
SMAC Moving Coil Actuators announces IP-rated products
SMAC Moving Coil Actuators has revealed the details for their dustproof and waterproof, IP65/IP67 product line. SMAC’s IP-rated products include the CBL35/CBL35C series electric cylinder, the CBL50/CBL50C series electric cylinder, the LAL95 series linear actuator, and the LCA50 series linear actuator. All dustproof and waterproof SMAC moving coil actuators include the ability to do work […]
What’s the difference between a piezo actuator and a piezo motor?
In the context of motion control, the term “motor” generally refers to a single electromechanical device that produces rotary or linear motion to drive a system, while the term “actuator” typically refers to an integrated mechanical system that is driven by a motor. But in the context of piezo drives, the term “actuator” refers to […]
High-speed linear actuators: What qualifies them as high speed?
Like many terms used in the linear motion industry such as “heavy duty” and “miniature” and”corrosion-resistant” to name a few, there is no industry standard that specifies what constitutes a “high-speed” linear actuator. Nevertheless, there are some general guidelines that manufacturers follow when classifying and marketing their actuators as high speed. These guidelines are typically […]
