AC to DC Motor Controller

A DC motor controller manipulates the position, speed, or torque of a DC-powered motor and easily reverses, so the DC motor drive 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.

The DC motor speed controller function 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 motor 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.

Generate Electricity Using DC Motor - Demonstration of Overunity - Free Energy with DC Motor

A DC motor can be used to generate electricity, providing a source of free energy. This process is known as overunity, and it can be used to power homes and businesses. By harnessing the power of the sun and wind, DC motors can provide a sustainable and renewable source of energy.

🌀 Nikola Tesla's Ether Technology:
💠 Harnessing the power of back electromagnetic fields (Back EMF)
💠 Back EMF generates Lenz's Force in generator 💠 When the output energy is not affected by the Lenz (free) force, a self-powered mechanism will be established from the AC generator head to the induction motor. And the kinetic energy of the induction motor at that time was only supposed to stir the Ether by Nikola Tesla's "Rotating Magnetic Field". That's the mechanism for a Free Energy AC generator - no fuel needed - Self-powered generator.

How to control the speed of AC and DC motors?

Control an alternating current (AC) induction motor by:

Change the frequency of the AC current
Voltage change

Speed control of a direct current (DC) induction motor includes the following main methods:

Varies applied voltage with brush motor
Changing the applied current with brush motor
Variable frequency of applied current and voltage with brushless DC motor. Because the current has a trapezoidal or rectangular pulse pattern, the current on the graph jumps step by step. This brushless motor can be stepper motor.

With motors with built-in AC to DC conversion, or vice versa, DC to AC, the motor's speed control (regulating) mechanism is a diverse combination. A common combination is an AC or DC motor with a built-in speed regulator that converts AC to DC, and then DC to AC. At this time, the AC is adjusted to an arbitrary frequency by an electronic circuit, leading to the speed of the AC motor being controlled.

Built-in device in DC motor for speed control with AC input

With brushless DC motors, speed control or control usually uses the method of changing the frequency of the step voltage (with trapezoidal or rectangular shape, DC pulse). And of course, the input is AC, after passing through this device will be converted to DC with a customized frequency.

Versatile device that converts AC to DC and adjusts frequency and amplitude of step voltage - or AC to DC Motor Controller

Stepper motor is in the form of brushless DC motor, it has higher efficiency than ordinary DC and AC motor. The brushless DC motor is a typical device for using electronic technology in it. Obviously, this brushless DC motor is an indispensable device in mechatronics. However, DC motors are quite expensive. So the next part will be looking for DC motor with AC input, built in so called "AC to DC Motor Controller" but affordable.
