Biomedical applications, such as pipetting and sample handling require the precise dispensing of fluids, on the order of micro-milliliters (or micro-mils), with margins of error lower than 5%. Equipment that fails to meet these stringent dispensing and accuracy requirements is simply unacceptable in the bio-medical market; this leads to erroneous results.
The ElectroCraft hybrid stepper motors, when combined with an integrated fine pitch lead screw or ball screw, this hybrid stepper linear actuator can provide micro-mil resolution with sub-micro-mil accuracy.
As automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) become more commonplace in warehouses and factories, design engineers are working on next generation platforms that can move faster and more efficiently while continuing to operate safely in collaboration with their human counterparts.
ElectroCraft offers a unique, integrated wheel drive platform, which provides increased performance and reliability at an affordable price compared to traditional motor/gearbox/wheel combinations (Figure 1).
Among the challenges that design and control engineers must address are the pairing of motors with compatible drive electronics. Motors and drives must be properly matched and configured to ensure compatibility and optimal performance in regard to current, voltage, power and control requirements. Incompatibilities can lead to several problems such as motor overheating, excessive noise, inaccurate positioning, poor torque capability or fluctuating speed. Although these challenges can be daunting, there are solutions available to provide an affordable and easy-to-use platform that minimizes potential compatibility issues.
DC motors are motion components that take electrical power in the form of direct current (or some manipulated form of direct current) and convert it into mechanical rotation. Brushless DC motors do this through the use of magnetic fields that arise from the electric currents to spur rotation of a rotor fixed with an output shaft. Output torque and speed depends on the electrical input and motor design.
In this Design Guide, the editors of Design World detail the most common dc motor types as well common ways to quantify their output during the design engineering process.
ElectroCraft fractional horsepower (FHP) motor and motion control products are known for their durability, reliability and high performance, making them a top choice for customers in various industries. This article serves to better acquaint the reader with the ElectroCraft motor and servo drive product offer, this article will review: BLDC motor proliferation, the need for more sophisticated (but easy to use) servo motor drives, and the decision to buy versus make servo drive and motor control systems.
Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) are key elements in optimizing the efficiency and profitability of an automated warehouse. Minimizing the total cost of ownership (TCO) of the AGV or AMR is a must, and this depends heavily on the design of its drivetrain. If the OEM uses well-designed, proven components, the mobile platform will provide many years of service, handling cumbersome, heavy loads efficiently with minimal downtime for maintenance.

In order to more efficiently utilize energy and reduce emissions in the oil & gas extraction process, our customer required an electric motor and drive solution for a glycol circulation pump that was currently being powered by a methane fueled combustion engine.
Torque density and speed requirements of a motion control system are often at odds with space constraints. In new system designs, the trend toward miniaturization continues to reduce size, weight and, ultimately, cost. This trend is also driving the need for highly efficient brushless DC (BLDC) motor solutions that can fulfill performance requirements in a much smaller frame size.
