Drives in Protective Enclosures
Many applications require sealed drive enclosures to protect against dust sediments and liquid contaminants found on the factory floor and other places where drives might be installed.
Drives for Multiple Motors Operating One at the Time
Drives are programmed for multiple spindles (motors) so that each motor, when properly selected, operates with its ideal drive output.
Drives for Multiple Motors Operating Simultaneously
If all of the spindles (motors) operating on a machine are identical and if all of them run at the same speed at any given time, it is often most economical to use one larger drive to operate all of these spindles.
Universal Drives for Spindle Testing
Companies which repair (rebuild) high speed motors and motorized spindles, need to run each spindle after repair to make sure their electrical integrity, vibration, temperature, and everything else is satisfactory.
Drive Systems for Spin-Tests and Dynamometers
We specialize in drive systems for spin testing and load testing (dynamometers) for high rotational speeds.
Drives for 2 Phase Motors
We provide drive solutions for 2 phase motors.
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.
DC Powered AC Motor Drives
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.
400 Hz Line Powered AC Motor Drives
These custom drives operate from 400 Hz AC line voltage which is typically found on aircrafts and marine vessels.
Drives/Converters for Static Applications (for Loads Other than Motors)
By modifying our standard drive products and by using the building-block approach, SPINDEL Electronics can quickly and efficiently design and manufacture power electronics converters for various static applications.
Motor Filter Reactors (Inductors, Chokes)
Motor filter reactors (or chokes) filter motor voltage and current, thus improving motor life and electrical noise levels within the application. Please contact us if you have problems with motor temperature or motor insulation life.
Motor L-C Filters, Sinusoidal Filters
Motor L-C filters consist of filter reactor (inductor, choke) and capacitors. They are used on the output of PWM (Pulse Width Modulated) drives. Typically, they reduce the motor current ripple to much lower levels than reactors only, and they eliminate voltage pulses.
Drive Output High Frequency Transformers
Drive output high frequency transformers match the rated drive output voltage with motor rated voltage. On PWM (Pulse Width Modulated) drives, the rated drive output voltage is typically defined by the line voltage (mains) to which the drive is connected, while the motor rated voltage is often given and cannot be changed.
Scott-T Transformers for 2 Phase Motors
Some motors/spindles, especially the older ones, are built as 2 phase motors. Stator windings on such spindles consists of two coils, resulting in four available stator wires.
Load Banks for Drives and Generators
Load banks are typically custom made per application. Load elements consist of power resistors and inductors which are sized to match the required load points.
