Custom Drives & Custom Converters
Ultra High Frequency Drives
When the application requires fundamental motor frequencies over 6000 Hz (over 360,000 RPM for 2 pole motors), we modify our standard drives to increase fundamental motor frequencies to achieve motor speeds over 1 million RPM.
Please let us know your ultra high speed motor nameplate data (RPM, frequency, voltage, rated power/current) and we will offer a matching drive.
DC Powered AC Motor Drives
With the growth of renewable energy industry and “green technologies” came the increased need for AC motor drives operating pumps, compressors, turbo-chargers, generators, and other machines, which get their power from a DC source.
The DC source used can be a battery, a fuel-cell, an array of solar Photovoltaic (PV) panels, rectified generator voltage, or any other DC power supply.
As the requirements vary widely, especially in regards to the DC source (minimum and maximum DC voltage, maximum safe DC current etc.), these drives are custom made per application. In order to minimize cost and time, building blocks from standard drives are used whenever possible.
400 HZ Line Powered AC Motor Drives
These custom drives operate from 400 Hz AC line voltage which is typically found on aircraft and marine vessels.
They can run loads like compressors or pumps, generators, various test equipment, or auxiliary equipment.
Usually, these are modified stock drives, sometimes built with aluminum enclosures for reduced weight.
Drives/Converters for Static Applications
By modifying our standard products and by using the building-block approach, SPINDEL Electronics can quickly and efficiently design and manufacture power electronics converters for various applications such as vibration welding, ultrasonic welding, induction heating, AC and DC custom power supplies, and custom made converters for OEMs. We are skilled in efficiently modifying control algorithms to fit your process’ needs.
AC source configurations include AC/AC and DC/AC converters, using single phase, two phase, and three phase inverters in H-bridge or three phase bridge configurations, with and without input to output isolation.
DC source configurations include DC/DC converters in buck (step-down) and boost (step-up) configurations, with and without input to output isolation.
