CORMAK Variable Frequency Drives – Smooth Speed Adjustment and Motor Control

CORMAK variable frequency drives are designed to regulate the speed and control the operation of three-phase motors. They provide stepless speed adjustment, soft starting, controlled stopping and motor direction reversal. Advanced control functions enable drive operation to be tailored to the requirements of each machine, improving ease of use and offering greater flexibility in speed adjustment.

The CORMAK range includes 230 V and 400 V variable frequency drives, suitable for smaller workshop equipment and industrial machinery alike.

Where Are Variable Frequency Drives Used?

Variable frequency drives (VFDs) are used wherever motor speed adjustment and greater control over machine operation are required. Typical applications include lathes, milling machines, drilling machines, grinders, conveyors, pumps, fans and other equipment fitted with suitably specified three-phase motors.

A variable frequency drive allows the motor speed to be matched to the task, reduces sudden jolts during start-up and provides smoother transitions between different operating speeds.

Key Benefits of CORMAK Variable Frequency Drives

Stepless speed control – adjust motor speed to suit the task being performed.
Soft starting and stopping – reduces sudden loads on mechanical components.
Motor direction reversal – enables motor operation to be controlled in both directions.
Vector control – provides more precise motor control under varying load conditions.
Torque support – helps maintain the required drive torque at lower motor speeds.
Convenient operation – allows control via the inverter's control panel or suitably connected push buttons and a potentiometer.
Automated operation – selected functions allow operating speeds and simple operating sequences to be programmed.
Integration with automation systems – enables communication with compatible control systems.
Protective functions – monitor abnormal drive operating conditions.

Single-Phase 230 V and Three-Phase 400 V Variable Frequency Drives

The CORMAK range includes variable frequency drives with 230 V single-phase and 400 V three-phase power supplies. This allows you to select a drive that matches the available electrical supply and motor specifications.

Variable frequency drives with a single-phase input can also control a suitably compatible three-phase motor in locations where a three-phase power supply is not available.

How to Choose the Right Variable Frequency Drive

When selecting a variable frequency drive, the main factors to consider are motor power, rated current, supply voltage and the type of machine being driven. It is also important to establish whether the motor starts under load and what speed control range is required.

A correctly specified variable frequency drive allows you to make use of control functions suited to the equipment's actual operating conditions.
