Motor Gate Drivers

Microchip Technology (Chandler, AZ) offers the MCP8025 and MCP8026 3-phase brushless DC (BLDC) motor gate drivers with integrated power module, LIN transceiver, and sleep mode. The devices can power the dsPIC® digital signal controllers (DSCs) and PIC® microcontrollers (MCUs), driving MOSFETs, sensing current, preventing short circuits, outputting zero crosses, controlling dead time and blanking time, and monitoring for fault conditions such as over/under-voltage, over-temperature, and other thermal warnings.

HEV Motors

Parker’s Electromechanical Automation Division (Rohnert Park, CA) announced the GVM142 HEV motors. The generator and auxiliary motor series is an electric machine intended for use in electric and hybrid electric vehicle (HEV) accessory applications such as high-power alternator replacements and electrohydraulic pump control. They feature a 142-mm frame size with an SAE A adapter mount to be close-coupled to hydraulic pumps. Within this frame size, there are three rotor lengths and dozens of winding variations that enable more than 100 combinations of base speed and power output for ultimate scalability and fine-tuning to the vehicle’s exact power generation or electrohydraulic requirements. The motors have rated power from 2.6kW to 30kW+, rated torque up to 36Nm, rated speed range from 1600 to 9800 RPM, peak power densities up to 3.7 kw/kg, operating voltages from 24VDC to 800VDC, and SAE J1455 environmental standards.

Positioning System

Physik Instrumente (Auburn, MA) offers the H-850KMLD 6-axis hexapod positioning system with 1,000-pound load capacity that provides 1-μm minimum incremental motion over a 100-mm travel range in XY, and 0.5-μm in the Z direction. Repeatability in the three linear axes is ±1μm, and ±5μrad/9μrad in the rotary axes. The hexapods include a controller and software package. The dedicated C-887 hexapod multiaxis-vector controller is commanded directly in Cartesian coordinates. The user can specify a random pivot point in space with a single software command. LabVIEW and text-based programming languages under Microsoft Windows or Linux are supported by libraries and program examples. For loads above 2,000 pounds, standard H-845 and custom hexapods are available.
