Frequently Asked Questions (FAQ)

Resolve your queries from the below FAQ's related to Voltage Drives Manufacturer & Supplier in India.
What are the advantages of using voltage drives?

Voltage drives are prized for their:

  • High Starting Torque: Excellent for heavy loads that must start from a standstill.

  • Simplicity: The relationship between voltage and speed is easy to understand and maintain.

  • Cost Effectiveness: For specific high-horsepower applications, DC voltage drives can be less expensive than AC equivalents.

  • Wide Speed Range: They can operate effectively at very low speeds without the cogging issues seen in some other systems.

What are the main components of a voltage drive?

A typical voltage drive system includes:

  • Rectifier Bridge: Converts the AC supply into DC.

  • Control Circuit: The logic center that monitors speed and adjusts output.

  • Filter: Smooths the DC signal to reduce electrical ripple.

  • Field Controller: Manages the magnetic field in the motor to optimize torque.

How does a DC voltage drive differ from an AC drive?
A DC voltage drive converts incoming AC power into a variable DC voltage to control a DC motor. An AC drive (VFD) converts AC to DC and then back to a variable frequency AC signal. Voltage drives are generally simpler in design and are often used in applications requiring high torque at low speeds or precise tension control.
What maintenance do voltage drives require?

Because many voltage drives operate in heavy industrial environments, they require:

  • Heat Sink Cleaning: To prevent the power semiconductors from overheating.

  • Capacitor Inspection: Checking for leaks or swelling in the filtering section.

  • Brush Inspection: Since these drives often run DC motors, the carbon brushes in the motor must be checked regularly for wear to prevent voltage arcing.

What is the role of Thyristors or SCRs in these drives?
Silicon Controlled Rectifiers (SCRs) are the high-speed electronic switches used in most industrial voltage drives. By changing the firing angle—the exact moment the switch turns on during the electrical cycle—the drive determines how much of the voltage wave is passed to the motor, effectively lowering or raising the average voltage.
What causes a voltage drive to trip on an overvoltage fault?
An overvoltage fault occurs when the voltage in the internal DC bus exceeds safe limits. This often happens during rapid deceleration if the energy being pushed back from the motor has nowhere to go. It can also be caused by a sudden spike in the incoming utility power lines.
Why is feedback important for voltage drives?
To maintain an exact speed under changing loads, the drive needs to know how fast the motor is actually spinning. This is done using an encoder or a tachometer generator. The drive compares this feedback signal to the user setpoint and automatically raises or lowers the voltage to correct any deviation.
Can voltage drives be used with AC motors?
Standard DC voltage drives cannot run AC induction motors. However, there are specialized controllers like Variacs or Triac-based dimmers that vary AC voltage for very simple loads like universal motors or fans. For industrial AC motors, a VFD is almost always the required choice instead of a simple voltage drive.
What is regenerative braking in a voltage drive?
In a regenerative drive, the system can reverse the flow of energy. When a motor needs to slow down a heavy load, it acts as a generator. The drive takes this energy and feeds it back into the main power grid rather than wasting it as heat. This increases efficiency and provides superior braking control.
What is the primary function of a voltage drive?
The main purpose of a voltage drive is to regulate the speed of a motor by increasing or decreasing the voltage delivered to the motor terminals. In DC motors, the rotational speed is directly proportional to the applied armature voltage. By precisely controlling this level, the drive allows for smooth acceleration and consistent operation at various speeds.
Can voltage drives be used with AC motors?
Standard DC voltage drives cannot run AC induction motors. However, there are specialized controllers like Variacs or Triac-based dimmers that vary AC voltage for very simple loads like universal motors or fans. For industrial AC motors, a VFD is almost always the required choice instead of a simple voltage drive.
