DESCRIPTION
The KBWD Pulse Width Modulated (PWM) DC motor
speed control provides excellent dynamic response to load
variations.The efficient PWM waveform produces an almost
pure DC current to the motor (form factor < 1.05) which has
several advantages over a conventional SCR control. The
PWM significantly lowers audible motor noise and provides
longer brush life. It also produces less motor heating which
allows a smaller, less costly motor to be used for most
applications. Another advantage of PWM is higher output
voltage which provides increased output speed. In addition,
pulse-by-pulse current sensing provides short circuit protection
and prevents control damage due to shorted motors.
A unique feature of the KBWD control is the Plug-in
Horsepower Resistor
IR Comp and Current Limit when the control is used on
various horsepower motors. The control contains armature
feedback which provides excellent load regulation.
The control contains quick disconnect terminals as
standard. A potentiometer (5K),
(0-5 VDC), or PWM microprocessor output can be used to
vary the output of the control.
