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.

RoboticsTomorrow.com - Q&A with ElecroCraft

We provide motion control solutions in the form of electric motors, drives and motion control solutions for OEM Customers who are unsatisfied with having to design around inflexible off-the-shelf products.

Sensorless Control of Brushless Motors

Many applications would benefit from a brushless motor without a sensor. There are various options for realizing this. A method developed by maxon is now setting new standards for precision and reliability.

Choosing the Right Seal for Industrial Robotics

Selecting the appropriate sealing solution is critical to ensure the robot performs as expected. For example, in many of our applications, we must balance friction requirements with sealing effectiveness.

Everything You Want to Know About Alpine Conveyors

The Alpine Conveyor is a compact spiral configuration commonly used as an accumulation or elevating buffer zone between machines or as a process step for cooling or drying. It can also be used for line balancing or product changeover purposes.

What is the Difference between Hexapod 6-DOF Alignment Systems vs Conventional Stacks of Stages?

When faced with a multi-axis alignment and positioning application, motion engineers typically assemble a system from a stack of individual linear and rotary stages. This approach works well for applications when only a few degrees of freedom are involved (e.g. XYZ).

How to Improve the Precision of Positioning Stages with ACS Dynamic Error Compensation

Precision motion systems always exhibit some amount of positioning inaccuracy (or position error) due to various factors. These errors can be measured using external measurement devices, such as a laser interferometer...

DC Motors as Generators

Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive.

Interview with Michael ImObersteg, Future Robotix

We are targeting those industries that require precise, small, high-torque motors and complementary components such as high precision planetary gearboxes, slip rings, sensors and encoders.

Piezoelectric and Piezoresistive Effects in Robotics

Below, we'll look at piezoelectric and piezoresistive effects. Neither of those is new, but engineers are applying them in creative ways within the field of robotics or through methods that may one day improve robotics.

Midwest Motion Case Study: Torque Transmission

They had the perfect motor and the planetary gearmotor, but finding the right angle gearbox, positioned between the two, designed to their specifications was the challenge.

Why Custom Robot Integrations With Rotary Index Drives Makes Financial Sense for a Variety of Manufacturing Applications

As manufacturing is increasingly interwoven with automation, companies seek cost-effective options for integrating rotary index drives with a variety of robotic applications such as spray painting, welding, assembly, material handling and more.

The Many Uses of Bellows

Bellows are most often used to protect critical components. Actuators used in motion control equipment are often exposed to contaminants ranging from dust and abrasive grit to metal chips and weld spatter.

 IPR Robotics - Right-Sized 7th Axis Robot Linear Rails

IPR Robotics - Right-Sized 7th Axis Robot Linear Rails

IPR Robotics offers a wide range of servo-driven 7th axis linear rails for industrial robots. These rails come in ten different sizes and are constructed from modular high strength extruded aluminum sections to handle payloads of 100 kg to 1600 kg or from steel to handle 2000 kg payloads. This variety of rail sizes allows each application to be sized correctly, controlling the space required and the price point. The drive train design of these rails utilizes helical gear-racks and is proven over 10 years to be repeatable and reliable, even in tough foundry applications.
