Description
Edge Miniature Piezo Motors
The Edge motor is the smallest industrial motor of its kind available in the marketplace today. Providing unlimited linear or rotary motion, the Edge motor offers extensive opportunities in applications that suit a wide range of industries. The Edge motor works with a uniquely designed, compact ASIC-based driver, and can be operated with any servo controller. The Edge can be easily integrated into most bearing structures, and is ideal for mass production opportunities.
Rotary Piezo Motor
The ER Motor family leverages the many advantages of our piezo technology, applied in a traditional motor housing. Utilizing a piezo drive inside the motor, the ER family offers silent motor operation with zero backlash (no gears) and built-in holding and braking without power consumption. Motors can be provided with a closed back, rear-shaft, or with a built in rotary encoder. Closed loop operation is supported with the S775 XCD card, which is a closed loop drive and control module. The S775 can be provided as a small board or chip level based controller for integration into other electronics.
Rotary Shutter
The RS08 is the first shutter of its kind, utilizing a silent, miniature piezo actuator in an 8mm x 20mm package including the drive electronics. The RS08 is designed to work from a 3.3v battery and supports travel ranges from 35° to 120°. Shutter blades can vary in size and material, up to a 25mm diameter paddle. Using a proprietary feedback system, the shutter is fully operational as a closed loop device, stopping on electrical limits to avoid any noise from a mechanical hardstop.
Rotary Actuator
The RS08A is the first actuator of its kind, utilizing a silent, miniature piezo actuator in an 8mm x 20mm package including the drive electronics. The RS08A is designed to work from a 3.3v battery and supports travel ranges from 35˚ to 120˚. The RS08A allows for user definable shutter blade or filter changer, based on appropriate motion analysis of mass and moment of inertia. A proprietary feedback system is integrated into the grid, for closed loop device operation, stopping on electrical limits to avoid any noise from a mechanical hardstop.
NUC Shutter
The S787 series of NUC shutter is designed to meet the most challenging operating conditions of infrared imaging systems. The S787 shutter operates linearly with a direct drive EDGE motor, providing the lightest weight configuration while maintaining the closest proximity to the FPA. The S787 series is provided with a 17mm x 15mm leaf that is capable of moving 15mm in 100mseconds. The moving blade is supported by the Edge – Actuator bearing structure on one side and an outboard shaft bearing to eliminate any blade deflection and vibration. Standard configurations utilize the Edge motor with a miniature position sensor, integral to the shutter assembly, for closed loop operation. The shutter is supported by our ASIC that closes the position loop and serves as a drive & control.
Linear Filter Changer
The LF14 Linear Filter Changer is designed to meet the most challenging operating conditions of optical systems. The LF14 operates linearly with a direct drive Edge motor, providing the lightest weight configuration while maintaining the closest back working distance. The LF14 is provided with a blade that can accommodate different filter diameters and is capable of moving 14mm in 100 msec. The filter housing is supported by the Edge-Actuator bearing structure on one side and an outboard shaft bearing on the other, to eliminate any deflection or vibration. Standard configurations utilize the Edge motor with a miniature position sensor, integral to the filter changer assembly, for closed loop operation. The filter changer is supported by our ASIC that closes the velocity loop and serves as a drive & control.
Miniature Rotary Stage
Used for IMU Northfinding products,the S840 Rotary module contains a 50,000 cpr precision optical encoder (external interpolator), with the Edge motor technology and the XCD drive/control. This integrated design consists of a complete motion solution, including the motors, bearings, encoder, drive & control captured in a 30mm cube. The outside configuration can be adapted to support different customer electronics (Mounting Orientation), while the rotary module moves 90° – for a precise quartering process. The S840 is designed for a calibration process of an IMU (inertial measurement unit) to eliminate the drift and improve north finding precision. It is intended to reduce the cycle time and improve the precision based on current IMU availability.
Miniature Drive Controller
The XCD – Drive & Control redefines the art of miniaturized drive and control electronics with the smallest hardware for operating piezo ceramic servo motors. The XCD provides complete servo control for the OEM market, coupled with the power stage and drive electronics on one board. XCD will have an OEM specific, motherboard for connecting to the motor, position sensor, communication and power. The XCD for the Edge motor is provided as a single axis board which can operate in the ‘AB5’ mode with brake on/off, or in the more traditional AB1A mode. The XCD for the Edge motors accepts a single ended encoder signal and is programmed via an IIC interface and the NanoCommander user software.
Miniature Controller “Chip”
The XCD drive & control is a miniature closed loop servo control with the smallest hardware for operating piezo ceramic servo motors. The XCD provides complete servo control for Security market applications with a built in motor driver. The XCD component is provided on a chip level and can be integrated into user electronics with the addition of a motor power stage. The component level product will accept single ended or differential encoder input (motor size dependent) and is programmed via an IIC interface and our NanoCommander user software.
