MOTOR CHALLENGE 5: Choosing the Right Type of Stepper Motor for Your Application

Posted by Johann Tang on Nov 12, 2018 8:30:00 AM

Stepper motors are popular for their ability to position accurately as well as their ease of use.  Both the amount of rotation and the speed are controlled easily with the same digital square wave pulse signal.  Unlike servo motors, stepper motors do not need an encoder to operate.  Example applications of stepper motors are CNC machines, index tables, robotics, scanners, and more recently, 3D printers.

Automation is great for repetitive tasks, such as test fixtures for a process that has to repeated.  In this post, we will explain how to perform a reciprocating motion (back and forth cycles) with a product that does not require a PLC or external presence sensors, which can help speed up design cycles.

MOTOR CHALLENGE 3: Synchronizing Speeds of Two Motors

Posted by Johann Tang on Oct 15, 2018 9:00:00 AM

There are a variety of ways to synchronize the speed of multiple motors.  In this blog post, we will explain another advantage of using brushless motors systems, which is its ability to set speeds accurately and be able to synchronize speeds on multiple axes easily .  Brushless motors utilize built-in hall-effect sensors to regulate speed.  Even if the load, input voltage, or temperature fluctuates, the speed regulation will always be under +/-0.2% or better.

MOTOR CHALLENGE 2: Designing Lighter Equipment by Reducing Motor Mass

Posted by Johann Tang on Oct 1, 2018 8:32:18 AM

With the growing popularity of efficient brushless motors, replacing AC motors with these motors brings several advantages.  In this blog post, we will uncover one of the advantages that can benefit lighter and compact equipment designs.  If we just look at the motors, brushless motors are much more power efficient than AC induction motors.  This means a smaller brushless motor can do the work of a bigger AC motor.  With recent trends in efficiency, brushless motors should be considered during the motor selection process for new designs.

MOTOR CHALLENGE 1: Minimize Machine Footprint with Right-Angle Gear Motors

Posted by Johann Tang on Oct 1, 2018 8:31:15 AM

Parallel shaft gear motors are the standard configuration in the industry.  However, right angle gear motors are gaining popularity for its ability to minimize the footprint of a machine, such as a conveyor.  Another factor that should be considered is the type of gears used in the gearhead.  While worm gear technology is popular, its gear efficiency can vary from 50~90% depending on gear ratio.  On the other hand, hypoid gear technology keeps its efficiency at 80~95% regardless of gear ratio.  Higher gear efficiency allows more torque to be transferred from the motor to the load shaft, and sometimes allows even smaller motors to be used.
