Versa Drives specializes in VFD, brushless dc motors and drives and custom designed motor control solutions for Original Equipment Manufacturers. A highly experienced team of engineers understand the requirement of the customers to develop Variable Frequency Drives, BLDC motors & drives using state of the art design and simulation tools.
WHAT IS A VARIABLE FREQUENCY DRIVE (VFD)?
The Variable Frequency Drive for AC motors, also known as AC drive, is an electronic device which receives energy from a fixed frequency fixed voltage AC source (either single phase or three phase) and converts it into a variable voltage (or current), variable frequency three phase supply for a three phase motor. In so doing it gives the ability to run the motor at different speeds. Hence it comes under the category of variable speed drives.
WHERE ARE VFDs USED?
- Pumps
- Fans & Compressors
- Automatic doors
- Textile machines
- Tape winders
- Treadmills
- Whole body vibrating machines
- Milk Separators
- Polishing & Grinding machines
- Blowers
- Printing & Packaging machines
- Food processing machines
- Appliances
PRODUCTS
Custom Designed Variable Frequency Drives (VFD)
Versa Drives make custom designed variable frequency drives suitable for Original Equipment Manufacturers (OEMs). The advantages of using Versa Drives are:
- Flexibility of using ACIM, BLDCM, or PMSM
- Inputs/outputs as required
- Application specific control functions
- Advanced user interface features
- Power factor correction
- Conformance to mandatory standards
- Adaptability to working environment
- Desired size & shape
- Economical
These drives, as they are also called as AC drives, AC inverters, variable speed drives, adjustable frequency drives, can be used with following types of motors,
- AC induction,
- BLDC and
- PMSM.
Brushless DC Motors & Drives
Versa Drives has the capability to design BLDC motors and compatible drives for use in appliances and machines. Design and simulation tools are available to arrive at an optimum design for cost and performance targets.
Versa Drives is the ideal source for OEMs who are looking for a complete motor control solution. Currently BLDC motors and drives are being targeted at products that use inefficient single phase induction or universal motors to save energy.
As a first step Versa Drives has made a Super energy efficient ceiling fan and released it in the market in the brand name Superfan.
TECHNOLOGY
Drives for variety of motors
- AC Induction motor, Three phase and single phase
- BLDC motor
- PMSM

DC bus operated inverter drives
Versa Drives has developed drives that contain only the inverter stage that get power from DC bus. These drives can have the required inputs/outputs for control functions as per specifications.
BLDC and PMSM motors
Versa Drives has developed BLDC motor and PMSM motors spanning 30W to 0.75kW. These motors can be adapted in shape and size to the application needs. The motors can be outer rotor or inner rotor. The motors can be supplied along with customised BLDC and PMSM drives.
Standards & Certifications
Versa Drives Private Limited is an ISO9001:2015 certified company. Versa Drives designs drives that conform to following standards:
- IEC/EN 61000 EMC immunity standard
- EN 55011 emission standard
- CE marking
- UL & CSA safety standards
- ROHS, MDD directives
The certification is done at the request of the customer.
Power Factor Control
Versa Drives can incorporate power factor control at the front end to reduce the harmonics. In addition these drives can be used in wide range of input voltage of 90 to 260V that enables to use the same model for North American, European and Asian markets.
