Apex Dynamics releases the new Ultra Compact Integrated Geared Pulley Drive AL series. The AL eliminates the need for a right angle gearbox, couplings and or additional bearings, in turn, reducing cost, increasing performance, and reducing parts and engineering time from the system.
The AL series utilizes a fixed planet design, which allows the output housing of the gearbox to drive the pulley versus a standard shaft driven system. This new technology and design allows the pulley to be centered in between two high capacity bearings which increases stiffness and radial load capacities to over 2 times competitive models.
The True Helical gear design increases tooth-to-tooth contact ratio by over 33% vs. the standard spur gearing geometry. The Helix angle is optimized and produces smooth and quiet operation at extreme speeds. (Less than 2 arc-min, less than 56dB, up to 10,000rpms input).
The product is offered in 7 sizes (70mm thru 280mm) and is equipped with standard single & double stage ratios (2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90). Covered by the industry leading 5-year tip to toe warranty and delivery is guaranteed with in two weeks or it’s FREE.
When it comes to linear motion, there is always a tradeoff between speed, accuracy, load capacity, and length of travel. Nexen has created an innovative new technology that helps ease these tradeoffs. Their Roller Pinion System (RPS) combines the advantages of linear motors, ballscrews, and belt drives to provide fast linear motion with zero backlash, high accuracy, and long travels.
With traditional rack and pinion systems, the pinion gear teeth slide along the rack teeth as the pinion rotates. To reduce wear and friction, a small clearance is required between the rack teeth and pinion teeth. Depending on the application, this may introduce too much inaccuracy. For higher accuracy, a ballscrew might be used, but ballscrews have a limited length and speed. Linear motors address the speed and length issue, but the cost of long magnet tracks can be prohibitive.
The RPS system addresses the accuracy and wear issues by using bearing supported rollers and a special rack tooth profile. The rollers meet each tooth along a tangent path and smoothly roll down the tooth face, as opposed to a pinion which slaps into the tooth and then slides down its face. This increases life and lowers noise. The tooth profile is designed so that two rollers are loaded in opposition at all times, providing zero backlash.
The RPS system can achieve speeds up to 11 m/s and provide dynamic thrust up to 14000 N (3150 lbf). Racks can be assembled together in 0.5 and 1 meter increments, allowing unlimited travel lengths. As shown with the sample data below, the system’s accuracy is better than +/- 30 microns and does not vary with travel distance.
The video below shows the RPS system in action.
AutomationSolutions often has to handle projects requiring high power and low voltage. For example, the motors that drive the wheels on mobile robots need a lot of current to generate high torque, but the voltage available from the robot’s batteries is often just 12 VDC. AMC’s AZ series of board-mount servo drives is expanding to meet exactly these kinds of needs.
 The AZ series is designed to drive brushed and brushless servo motors. To increase system reliability and to reduce cabling costs, the drive is designed for direct integration into your PCB. The drive interfaces with digital controllers that have analog +/-10V output. It requires only a single unregulated isolated DC power supply, and is fully RoHS (Reduction of Hazardous Substances) compliant.
The drive is available with peak current capability up to 40 A and continuous current up to 20 A. It supports voltages from 10 to 80 VDC. Options are available for torque control and velocity control with hall or encoder feedback.

Danaher Motion has introduced Linear Motioneering, a web-based linear motion system sizing and selection tool that enables OEMs and factory automation users to optimize machine design and operation in five simple steps. Linear Motioneering walks users through a thorough process for a slide table application to deliver all the data necessary to make a quick system selection. The system can provide immediate 3D CAD models in multiple formats, motor requirements, life and safety factor calculations, lead time and pricing information, and a single part number to order from that includes all specified options. Linear Motioneering is available for free at www.linearmotioneering.com.
Linear Motioneering users enter application parameters including mounting configuration, environmental conditions, positioning, loading and move requirements. With that information, the system recommends a choice of specific systems optimized to meet the demands of the particular application. The recommended product solution, including any accessories and motor mounts, is assigned a Smart Part Number that the machine builder can use to order the linear motion system with all accessories pre-mounted and ready for integration into the machine.
A motor interface selector allows users to enter motor dimensions, or any major manufacturer’s motor model number, and the system automatically configures the mating flange and coupling. Linear Motioneering also provides safety factors for critical system components that allows users to make a decision based not just on price, but on the safety margin of his or her selection. Users can change the move profile and calculate the resulting loads and safety factors on the fly. An environmental screen guides the user not only to the base system selection, but also displays appropriate options such as material and coatings that are suitable for that environment.
Linear Motioneering also includes a Configure Your Solution mode which provides all of the same deliverables as the Sizing and Selection mode, but is intended for those who are familiar with Danaher Motion products and want to quickly configure a part number. The Lookup by Part Number module is a way for repeat customers to confirm current pricing and part number configuration.
