How does an inverter control a motor?
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
What is a direct current (DC) inverter?
More than 730 people have received a free quote in the last 60 days. Enter details in under 3 minutes. In modern heating, ventilation, and air conditioning (HVAC) units, a direct current (DC) inverter is motor control technology that gives the system more control over the compressor power and speed.
How does a DC inverter work?
Compressors in a traditional HVAC unit operate at a fixed speed — if the system is on, the compressor will always be at 100%. A DC inverter controls the voltage to the compressor, and therefore its power and speed. Here’s how it does it: The inverter converts alternating current (AC) from the power supply to direct current.
Do you need an inverter for a motor control application?
For motor control applications, an inverter is not inherently required. The rotation speed (RPM) of a three-phase AC induction motor is determined by the equation RPM = 120 * f / P, where f is the frequency and P is the number of poles.
What is a brushless DC motor?
Since the brushless DC motor is dedicated to speed control, it can be used right away without going through the parameter setup or adjustment which is required for inverters and servo motors, saving time and effort. Brushless DC motor drivers are commonly available in AC or DC voltage input. This allows for greater design flexibility.
Which inverter is most suitable for variable speed motor control?
An inverter, which is capable of dynamically changing the DC frequency, is most suitable for variable-speed motor control applications. Theoretically, the rotation speed of a motor can be controlled by varying only the frequency.

Traditionally DC power conversion was achieved through a motor generator set, where a motor operating on DC power directly turned a generator to produce the required AC power. The opposite of this, an AC motor driving a DC generator was called a converter, hence the name inverter when applied to a DC to AC gen-set, the name stuck.
