Performance Motion Devices Delivers on Customer Requests for Additional Motion Control Options

AACC 2018 and Westford, MA – July 31, 2018  Performance Motion Devices, Inc., a provider of innovative, high performance integrated circuits, boards and drive-based motion control solutions to OEMs around the globe, today announced that its ATLAS® digital amplifiers, featuring the highest power density in the industry, can now be used with third party microprocessors or field programmable gate arrays (FPGAs) via Serial Peripheral Interface (SPI) communications.

ATLAS Digital Amplifier Has New Communication CapabilitiesOriginally designed to be used in conjunction with Performance Motion Devices’ Magellan® motion control ICs, ATLAS digital amplifiers can now communicate through SPI with third party controllers, significantly increasing the range of applications and designs where ATLAS can be deployed. ATLAS digital amplifiers are suitable for robotics, medical devices, laboratory equipment, scientific instruments, fan and pump control, precision motion and industrial motor control.

“Adding new controller options to ATLAS amplifiers’ already unique combination of high power density, digital current loop, and IoT capability results in a powerful amplifier that customers can use in a wider variety of motion control applications,” said Chuck Lewin, President and CEO of Performance Motion Devices. “With this announcement we are capitalizing on a clear opportunity to better serve our customers and greatly expand the market penetration of our ATLAS digital amplifiers.”

ATLAS digital amplifiers are compact single-axis modules that provide high-performance torque control of DC brush, brushless DC and step motors. Featuring the highest power density in the industry, ATLAS versions are available in 75W, 250W, and 500W power configurations in two module sizes: 27 x 27 x 13mm and 39 x 39 x 15mm. For additional flexibility, ATLAS package options can be mounted to a printed circuit board in either vertical or horizontal configurations depending on customer preference.

ATLAS amplifiers integrate a field-oriented control (FOC) digital current loop, which enables finely-tuned motor current control and lower power consumption and noise. Further, ATLAS amplifiers can rapidly record IoT information such as commanded current vs. actual current, temperature, bus voltage, etc., enabling host processor access to critical motion control parameters. This capability allows engineers to monitor system performance and proactively address problems before they arise.

ATLAS digital amplifiers are powered from a single supply voltage, and provide automatic protection from over-current, under-voltage, over-voltage, over-temperature, and short circuit faults. Other advanced ATLAS features include; programmable gain parameters and performance trace. Originally designed to integrate seamlessly with Performance Motion Devices’ Magellan motion ICs, they can now also be used with FPGAs, digital signal processors, or general-purpose microprocessors.
