DC Motor Controls
American Control Electronics carries a wide selection of DC motor controls that exceed industry standards. A DC motor controller manipulates the position, speed, or torque of a DC-powered motor and easily reverses, so the DC current runs in the opposite direction. Enjoy higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and more. Select technology type, input voltage, output voltage, continuous current, enclosure, braking type, reversing type, and isolation.
DC motor speed control is perhaps the most common manipulation used in DC controllers. This speed can be controlled in four different ways: flux variation, armature voltage variation, a change in the supply voltage, and pulse width modulation (PWM). PWM is the technique commonly used for achieving speed control in a DC motor. It delivers energy through a series of pulses rather than a continuous signal. By altering the pulse width, the DC motor controller is able to regulate the energy flow to keep it consistent.
While less popular, DC motor torque control is achieved by a DC drive regulating the armature current. Since the armature current isn’t regulated, the motor can operate at whatever speed necessary to achieve the desired torque level. The torque level can remain constant achieving a “taper tension effect” for a fixed input reference and torque mode center winders. However, the machine operator can in some circumstances increase the torque set-point as diameter increases.
American Control Electronics offers a variety of DC motor controls that include various operation modes both separately and together. It simply depends on the application and needs of your motor control systems. However, due to such diversity, it can be difficult to find the DC motor controller that fits your mold. Be sure to understand the voltage ranges and types of control needed to properly operate your control system.
