STMicroelectronics reveals world’s smallest motor drivers
With the expansion of portable technology in everyday life, new tiny, low-power electric-motor drivers from STMicroelectronics, are enabling sophisticated battery-powered equipment to become smaller and more mobile with extended runtime. Controlling the motors at the heart of devices like portable medical pumps and drivers, personal wellness devices, portable point-of-sale devices, miniature robots, surveillance equipment, precision […]
Nexen introduces additional sizes of high-torque tooth clutches
Nexen Group, Inc. introduces Size 80 and 100 high-torque tooth clutches to deliver more torque and flexibility than other products on the market. This series consists of more than 45 clutches in multiple bore sizes designed to provide high torque in a small package, and configured to drive/hold large loads. Models are available as air […]
FAQ: How to calculate motor temperature (worst-case) under required load?
Edited by Zak Khan || Stepper motors like other motors deliver different levels of performance at different temperatures. In fact, most stepper motors are designed to operate at relatively high temperature without issue — even to 90° C in some cases. However, undersized motors are at risk of excessive heat (not to mention sluggish acceleration if […]
FAQ: How do I pick torque margin to prevent stepper motor stalls?
Edited by Zak Khan || Torque margin is the amount of extra torque capacity a stepper motor has to ensure successful operation without stepper motor stalls. A sufficient torque margin is critical when a motion design incorporates stepper motors for motion, as in many cases there’s no correction of motion if the motor is temporarily overloaded. Read […]
C&K introduces industry’s only subminiature DP3T vertically actuated slide switch series
C&K Components introduced the industry’s first subminiature, vertically actuated on-on-momentary slide switch series. The new JS207 Series slide switches feature a double-pole, triple throw (DP3T) configuration that can be used to replace a two-position slide switch, and a separate momentary push switch for applications that require the on-on-mom function. In addition, the entire line of proven […]
Groschopp announces AC Motor-Control combo with chassis enclosures
Groschopp, Inc. is currently setting apart its AC motor-control combo by implementing strategic compatibility design measures. When matched with Groschopp motors and gearmotors, the DA1225K-0 and DA1215K-0 reduce slip and increase efficiency better than other drives on the market. In addition, these AC controls exhibit the following characteristics: Short circuit protection Input voltage options: 115/208/230 […]
Rockwell Automation expands machinery safety system integrator program
Many manufacturers rely on system integrators to design and install compliant machinery safety solutions, but they often struggle to find the most capable provider. To help ease that process, Rockwell Automation continues to expand its global Machinery Safety System Integrator program. Three new members have joined in the first half of 2016, bringing the total […]
FAQ: How do programmable automation controllers (PACs) handle analog I/O and related controls?
By Steve Meyer || Analog inputs and outputs are generally associated with sensors. These in turn are the key to controlling real-world processes. So depending on the speed and resolution needed to measure events being controlled, analog inputs come in many performance ranges. Common sampling resolutions are 12 to 24 bit, and sampling frequencies range from kilohertz to […]
New Compact Encoders for OEM Designs
The new Pittman E21 family of 21mm optical incremental encoders satisfy the demands of volume OEM precision-motion control applications. The E21 represents a huge improvement over its predecessor with a 40% lower profile, multichannel outputs and options yielding up to 32 times the resolution and up to 24 times the frequency response. Creative packaging also […]
