If you have been to a used equipment auction and purchased a mill, lathe, drill press or other piece machinery with a three phase
motor and are looking for a low cost solution to power it with single phase power. This may be your low cost solution. Unlike
some of the electronic phase inverters that only output 2/3 of the power, this unit puts out 100% 3 phase power with 200% starting
torque. You will need to eliminate any other motor switches.
You will
connect the motor directly to the 3 terminals on the converter.
Otherwise the contacts from the old motor starter will allow feedback to the control that will damage the unit. The KB control
becomes the motor starter. The unit should be powered through an electric power disconnect.
When selecting drive size the motor amps cannot exceed the rated output amps of the control.
Standard Features:
Operates standard 208/230 VAC 3-phase AC motors, with 230 VAC  input single phase
Power Start provides more than 200% starting torque
30:1 speed range with full motor torque (Speed potentionmeter (pot) provided)
(Motor should be inverter rated if using speed control feature)
Controls 50hz and 60hz motors with a convenient jumper selection
Sinewave coded PWM-provides high motor torque and efficient operation
16 khz switching frequency-provides quite motor operations Motor overload protection
Jumper selections: Forward-stop-reverse/Enable-automatic-manual
You can use a 3-position toggle switch
Start 0-60,0-120, 0-50hz.
Trimpot adjustments: Minimum Speed-min, Maximum Speed-Max
Important Application Information:
Most fan-cooled (TEFC) 3-phase motors will overheat
if used with an inverter beyond a limited speed range at full rated torque. Therefore, it is
necessary to reduce motor load as speed is decreased.
Attention:
Your motor amps
cannot
exceed the rated output amps of the converter.
Motor can not be run through contacts. Motor to be wired directly to controller.
Note:
Speed potentiometer
must be connected
or the motor will not spin, without the pot
the speed is set at zero and you will burn the motor up. You will need to soldier leads
to the potentiometer and connect it to the control.
Not Recommended for use on air compressors
