DC Drives

KBMM DC Drive

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. 25A SCR’s and line and armature fusing further enhance reliability. KB’s exclusive Plug-in Horsepower Resistor® eliminates the need for recalibration when used over a wide range of motor horsepower. Standard features include trimpots for Min, Max, IR, CL and Linear Accel and Decel armature or tach feedback. Auto Inhibit, MOV transient protection, 5K pot and Noise Rejection Circuitry. Options: Auxiliary Heatsink, Barrier Terminal Options, and SI-6 Signal Isolator. Dimensions: 3.63” x 4.30” x 1.25” . Patented.

KBIC DC Drive

The KBIC® controls PM, Shunt and AC/DC motors over a range of 1/100-3 HP with only a few models. All models can be used on a wide range of motor horsepower by inserting the proper Plug-in Horsepower Resistor®. Speed range is 50:1 with load regulation of 1%. Features include Auto Inhibit®, Voltage Following, MOV transient protection, 5K speed pot and trimpot adjustments for Min, Max, Accel, IR and CL. Options include Auxiliary Heatsink, AC Line and Armature Fuse Kit, Barrier Terminal Options and SI-5 Signal Isolator. Dimensions: 3.63” x 4.30” x 1.25”. Patented.

KBWM DC Drive

The KBWM control is a compact version of our 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, and contains AC line and armature fusing and a barrier terminal connection block. The KB Plug-in Horsepower Resistor® automatically calibrates IR Comp and CL. Dimensions: 5.25" H x 3.70" W x 2.9" D.

KBRG DC Regenerative Drive

The KBRG™ is a full-wave regenerative control, capable of operating a DC motor (Permanent Magnet or Shunt) in a bidirectional mode. It provides 4-quadrant operation which allows forward and reverse torque in both speed directions. The KBRG™ contains many standard features, such as: armature and tach feedback, built-in horsepower selection, trimpots for Fwd CL, Rev CL, IR Comp, Response, Max Spd, Offset, Deadband, Fwd Accel, Rev Accel and Timed Current Limit. LED indicators for: Power On, Current Limit, Fwd Enable and Rev Enable. A 5K speed pot is included. Dimensions of the KBRG™: 7.7” x 10.0” x 2.5” (Mod. KBRG™-240D), x 3.35” (Mod. KBRG™-225D).

KBMG DC Regenerative Drive

The KBMG® is an ultracompact, full-wave regenerative drive capable of operating DC PM or Shunt motors in a bidirectional mode. Its 4-quadrant operation provides forward and reverse torque in both speed directions which allows the control to maintain constant speed with overhauling loads, provides rapid reversing and controlled braking. Because of its excellent controllability and response time, the KBMG can replace servos in many applications. The control is factory set for armature feedback, which provides up to 1% load regulation over a motor base speed of 50:1. Tach-generator feedback is also provided for superior load regulation if required. A simple jumper setting converts the KBMG to a torque control. In this mode, motor torque rather than motor speed is controlled.
