Design and Operation Features of a BDC Motor Controller

The design and functionality of a DC motor controller depend on the characteristics of the motor and the electronic system it powers. Using the example of a brushed DC motor controller, we'll consider its operating principles and circuit design.

Dual Loop Control: No More Gear Backlash

Can loads be positioned dynamically, with high precision and no oscillation, despite mechanical backlash and elastic components? Yes - using an intelligent system.

Motor Commutation: FOC vs. FEC

There are many commutation schemes, many of which have hardware implications. Right now, we'll take a look at Field Oriented Control (a well-established method of commutation) and Field Estimated Control (IQ's new method of commutation).

6 Ways to Use a Bottomless Conveyor

Bottomless conveyors, also called side-gripping conveyors, provide a simple solution for accessing the underside of a product for a range of applications. These applications include inspection, printing, labeling and edge sealing.

Under the Surface - Non-destructive Testing of Composite Materials

The portable inspection system iX-600 enables a non-contact and therefore guaranteed non-destructive inspection (NDI - Non-Destructive-Inspection) of composite materials. Testing can be carried out with regard to detachment, delamination or porosity.

Getting the Right Grip: Designing Soft and Sensitive Robotic Fingers

Scientists make a big leap in development of soft robotic grippers by integrating sensing mechanisms into 3D printable fingers.

3DMGQ7-GNSS/INS Dynamic Performance Test Report

GNSS and INS performance accuracy is generally tested in an ideal static environment, and often not representative of end use performance. Dynamic environments introduce error sources such as multipath, obscured sky view, vibration, inconsistent RTK data streams and more.

Integrated Wheel Drives Lower Cost of Mobile Robot Ownership

The lifetime cost of ownership of a mobile robot is largely influenced by the design of its drivetrain. If the OEM uses well designed and proven components, the mobile robot will provide many years of service with minimal downtime for maintenance.

Precision Micromotors in Defence Robots

The defence sector is a valuable contributor to the economy, providing a large number of jobs and investing in a number of industries. However the relationship is mutualistic, with advancements in industry benefitting the defence sector.

Without Micromotors Global Logistics Would Be Lost

Always more, always faster, always further everything needs to arrive at the right time at the right place - the global goods cycle keeps the economy running and is a challenge for everyone involved.

The Claxon Platform, a Quad CXP-12 PCIe Gen3 Frame Grabber

CXP-12 now offers the ability of transfer data at rates of 12.5 Gbps over a single cable up to 40m. Accompanied by the ability to power the camera from the PC via the cable is unique and unprecedented. No other interface can offer these options at these data rates currently.

A Lot of Power in a Very Small Space

Drive Systems evolved. Generally speaking, electric motors are not "lone wolves" but for most applications need to be combined with gearheads for speed reduction as well as encoders.

The Importance of the Speed-Torque Gradient in DC Motor Sizing

The speed / torque gradient is an indicator of a motor's performance. The smaller the value, the more powerful the motor and consequently the less motor speed varies with load variations. It is based on the quotient of ideal no-load speed and ideal stall torque.

Understanding the Motor Constant in DC Motor Sizing

One of the most often overlooked parameters of direct current motors (both brush and brushless) is the Km or motor constant. The motor constant (expressed as Km) defines the ability of a motor to transform electrical power into mechanical power.

The Importance of a Reliable Supply Chain for Robotics Companies

Friction in our supply chain -- delays or quality issues, for example -- directly impacts our bottom line. We're a quickly growing company and we need to be agile enough to take advantage of new opportunities as they arise.
