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 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.
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.
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.
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.
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.
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.
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.
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).
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...
Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive.
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.
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.
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 ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
