Teknic’s Motion Education Articles – free resources for servo/stepper applications

14 May 2021

Teknic's servo systems power hundreds of thousands of automated machines. To ensure their performance and reliability, the company has spent the past 35 years working with its OEM customers to select actuators, couplings, power supplies, and other components that will optimise their motion systems.

Teknic recently published Motion Education Articles that share its 35 years of practical field experience (no subscription required and free pdf downloads available). Articles include:

1) How to Choose the Best Linear Actuator for your Application

This discusses five types of linear actuators: Ball screws; Lead screws; Rack and pinions; Moving timing belts; and Fixed belts.

• Compare side-by-side specs for each actuator type, including acceleration, accuracy, and installed cost
• Read an analysis of the pros and cons of each type of actuator
• Get advice on how to get the most out of your actuator

2) Securing Mechanics to Motor Shafts

This reviews common methods for attaching mechanics to servo and stepper motors. These methods include: Clamps or split clamps; Adhesives; Keyless bushings; Keys and keyways; Set screws or grub screws; and Pinning.

For each attachment method, the article:

• Evaluates the pros and cons
• Identifies ideal use cases for each attachment method
• Recommends the overall best attachment methods

3) Selecting the Best Power Supply for your Application

This discusses the technical considerations unique to powering motors, and compares these three power supply types: 

• Unregulated, "bulk linear" supplies
• Regulated, PWM switching-mode supplies
• Hybrid, regulated "resonant mode" supplies

You'll see how move profiles and torque-speed curves are related to power supply selection, you'll get power/price comparisons, schematics, and recommendations based on decades of practical field experience. You'll even learn what modifications are needed with regulated and unregulated supplies in regenerative energy and high peak draw environments.
