KB Electronics KBWD Pulse Width Modulated Whisper-Drive
|
|
|
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.

KB Electronics KBTC Torque Controls
|
|
|
The KBTC-125 and KBTC-225 are designed to control a motor's torque, by controlling motor current. Unlike a traditional DC motor speed control, which controls voltage and limits current, the main potentiometer of the KBTC sets the current. The motor current will not vary over the speed range if the load is less than the current set point; the KBTC goes to maximum voltage.

KB Electronics KBWM DC Motor Speed Controls
|
|
|
The KBWM control is a compact version of the Multi Drive (KBMD). The control is packaged in an all-metal NEMA-1 enclosure. This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization.

KB Electronics KBMM DC Motor Speed Controls
|
|
|
The KBMM full-wave DC motor control is the ultimate in reliability and performance. Contains Direct-Fed™ current limit that helps protect the SCR power bridge against direct shorts and prevents demagnetization of PM motors.

KB Electronics KBWT High Current Pulse Width Modulated Whisper-Drive
|
|
|
The KBWT Pulse Width Modulated (PWM) DC motor speed controls provide excellent dynamic response to load variation. 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. PWM significantly lowers audible motor noise and provides longer brush life.

KB Electronics KBWS Pulse Width Modulated Whisper-Drive
|
|
|
The KBWS PWM (pulse width modulated) controls are designed to operate PWM and SCR rated Permanent Magnet motors ranging from 1/50 HP to 11/2 HP. They operate at a switching frequency greater than 16 kHz to provide high motor efficiency and quiet operation.
