Right Angle Gearheads: Why are Hypoid Gears Better Than Worm Gears?

Posted by Johann Tang on Apr 17, 2019 10:00:00 AM

Historically, worm gears have been known as the most common type of gears used in a right angle gearhead.  Their low cost and robust construction have been sufficient for general purpose applications.  However, they are inefficient at slower speeds (higher reduction ratios), produce a lot of heat, take up a lot of space, and require maintenance.  As efficiency standards became increasingly important globally, another type of gear is being adopted for right angle gearheads.

Simple Method to Limit Motor Operation Range for Robotics Safety (VIDEO)

Posted by Johann Tang on Apr 1, 2019 2:09:05 PM

In the world of industrial robotics, there are several types of robots typically offering multiple axes of motion for tasks such as parts assembly, material handling, or pick and place operations.  These include articulated robots, cartesian/gantry robots, SCARA robots, and Delta robots.  Variations of end effectors such as grippers, welders or part rotators can be mounted on the end of the arm to perform different tasks.  Depending on number of axes or load capacity, costs can easily add up.  Limiting the operation range for these robotic axes of motion is an easy way to prevent costly problems or safety issues later.

Torque Limit Application Example - Bottle Capping with BLDC Motors (VIDEO)

Posted by Johann Tang on Feb 15, 2019 1:00:00 PM

For applications where torque needs to be limited, an external mechanical torque limiter is typically required in addition to the motor system.  When the torque exceeds the limit, the torque limiter will either decouple the load or limit the torque by slipping.  An electric motor system's built-in torque limit function can simplify machine designs by eliminating this extra component.

Flexible Mounting Options for Compact Stepper Motor Drivers (VIDEO)

Posted by Johann Tang on Feb 1, 2019 11:00:00 AM

A driver is a must-have for any stepper motor.  In a stepper motor system, a driver controls how the motor operates based on signals received from the controller.  It is responsible for sending current through various phases in a stepper motor and also regulates the motor current (torque) and step resolution.  With recent trends of minimizing machine footprint, finding space to install drivers could be challenging.

Shorten Design Cycles for Mobile Robot Applications With Built-in Features & Functions

Posted by Johann Tang on Dec 15, 2018 12:00:00 PM

In the market of electric motors, there are products designed for general purpose applications, and there are motors designed for specialized applications, such as automated guided vehicles (AGVs) or autonomous mobile robots (AMRs).  While standard, general purpose motors work for most applications such as factory automation, sometimes, it may help shorten your design cycle by going with a motor system that already offers the features that you are planning to implement into your design.  In this post, we will summarize some of these features.
