What is a Variable Frequency Drive (VFD)?
A Variable Frequency Drive, or VFD, is an electric motor which varies the speed of an AC induction motor by varying the voltage and frequency of power to the motor. Essentially, it drives the motor at just the speed the process demands, not full speed all the time, the secret to energy savings and smooth control.
Types of Variable Frequency Drive:
Being as premier variable frequency drive manufacturers in Kenya, we provided different types which are given below.
By power conversion method
- AC-DC-AC (VSI): Most widely used type. It converts AC to DC via a rectifier and then again, the DC is converted to a variable-frequency AC for the motor via an inverter.
- AC-AC (Direct): Direct frequency drive in which AC power is converted directly into a variable-frequency AC output without the intermediate step of a DC conversion.
By method of control
- V/Hz Scalar Control: The least expensive and easiest to apply, best suited for applications such as centrifugal fans and pumps in variable frequency drive suppliers in Kenya.
- Sensorless Vector Control: Estimates motor flux in order to provide improved torque and speed control without an encoder.
- Closed-Loop Vector Control: Employing a speed encoder for the precision control, demanded on applications such as hoists and elevators in VFD in India.
- Direct Torque Control (DTC): A control technique where the torque is computed directly to achieve an ultra-high response time, typically in the absence of a feedback encoder.
By application or capability
- Regenerative Drives: Enables the motor to feed the energy back into the power supply in the case of braking or deceleration.
- Medium Voltage VFDs: High power, medium voltage VFDs.

Benefits/Features of Variable Frequency Drive:
As variable frequency drive suppliers in Kenya, we provided different Benefits which are given below.
- Massive Power Saving: By motor speed control to handle load, VFDs avoid motors from pulling more than required power, resulting in substantial electricity cost savings.
- Accurate Speed Control: Provides infinite speed control of the motor, enabling infinitesimal management of processes (e.g., flow, pressure, or tension) to attain precise manufacturing specifications in variable frequency drive exporters in Kenya.
- Less Mechanical Stress: The Variable Frequency Inverters eliminates high inrush current and immediate torque of direct-on-line (DOL) start, providing a soft "soft start" that will not damage motors, gears, and equipment.
- Improved System Power Factor: VFDs avoid creating the electrical system's power factor to stray away from unity, reducing utility penalties as well as maximizing the overall efficiency of your electrical facilities.
Key characteristics of Variable Frequency Drive:
As premier variable frequency drive exporters in Kenya, it determines different Key characteristics which are given below.
- Variable Output Frequency: The most critical function of a delta electronics variable frequency drive is its capacity to modulate the output AC frequency, which determines the motor operating speed (RPM) directly.
- Soft Start and Stop: VFDs can speed up motor speed in smooth steps and slow down motor speed in smooth steps as well, avoiding mechanical shock to the system and prolonging component life.
- Advanced Motor Protection: Variable frequency drive inverter, adjustable frequency drive continuously observes the motor running condition and offer inbuilt protection against repeated faults such as overcurrent, overheat, and loss of phase.
- Digital/Analog Control Interface: AC VFD Drive come with advanced keypads and terminals to allow convenient programming, monitoring, and interfacing with external control systems (such as PLCs) through digital inputs.
Applications of Variable Frequency Drive:
Serve as premier variable frequency drive dealers in Kenya, it is applicable in different sites which are given below.
- Pumps: Flow rates are controlled accurately by VFDs without wasting energy through inefficient throttling valves, and conserve a lot of energy, particularly in water treatment or HVAC application.
- Fans and Blowers: Low voltage AC variable frequency drive regulate air pressure and volume according to demand, which is indispensable for cooling towers and ventilation systems in order to conserve power and establish the ideal conditions.
- Compressors: VFDs ensure a constant air system pressure level by varying the motor speed, cutting wasteful cycling and machine mechanical wear by an astonishing percentage in variable frequency drive manufacturers in Kenya.
- Conveyor Systems: 90V frequency drive provide smooth acceleration and deceleration of material without damage to products and coordinated motion on complex assembly and sortation lines.
- Extruders and Mixers: Industrial power inverter AC drives offer high accuracy torque and speed to process broad-ranging materials, which is of top priority in plastics or food processing use to offer uniform high-quality output.
