Variable frequency drives are electric devices that provide accurate, intelligent demand-oriented motor speed control up to 90 kW. These high-quality motor control solutions deliver a simple, precise and energy-saving three-phase drive speed control solution used across a wide range of plant and factory automation applications.
Tectra Automation distributes the full range of Bosch Rexroth variable frequency drives for asynchronous AC motors across Africa.
For many companies, rising energy costs, reducing waste and achieving more environmentally friendly production are among the primary objectives in increasing productivity and profitability.
Optimising your drive technology with our reliable, robust and easy-to-use frequency and voltage variable frequency drive solutions can help lower your electric motor’s energy consumption and improve energy savings by up to 700% and are superior to soft starters.
EFC frequency converters provide precise speed and torque control for AC motors up to 90 kW. Ideal in a range of general and specialised applications.

Our field-oriented frequency converter is designed for the power range of 400 to 90 kW. 3 control modes are available in our range.
VIEW PRODUCTSignificant energy savings: these VFD frequency drives can reduce electricity consumption by up to 80%, especially in pump and fan applications, by intelligently adjusting the motor's speed to the actual demand of the process rather than continuously operating at full speed.
Extended equipment lifespan: the freq drives offer controlled, smooth starting and stopping. This lessens the wear and tear on motors, belts, gears, bearings, and driven machinery by removing the severe mechanical shocks connected to direct-on-line starting.
Decreased electrical stress: the variable frequency drives reduce the enormous inrush current surges that usually occur during startup by regulating the motor's acceleration. Doing this prevents peak demand penalties on your power bill and safeguards the electrical network.
Enhanced process precision: our VFD drives provide extremely precise control over torque and speed. This enables equipment (such as packing lines, mixers, and conveyors) to operate at the precise ideal speed for a given task.
Wide power range: capable of supporting AC electric motors from 400 W (0.4 kW) to 90 kW, it can be configured for both Heavy-Duty (HD) and Normal-Duty (ND) applications.
Advanced control technology: equipped with various control modes, such as V/f (Voltage/Frequency) control, SVC (Sensorless Vector Control), and FOC (Field Oriented Control), allowing for precise management of speed and torque.
Built-in components: each frequency drive unit is provided with a built-in brake chopper (for models up to 22 kW) and an integrated mains filter, which helps to reduce panel space requirements and installation expenses.
Detachable control panel: includes a removable interface with a potentiometer, stop/start buttons, and a digital display that can be mounted externally on an electrical cabinet door, ensuring easy and safe access to parameter adjustments and diagnostics.
Built-in safety: features Safe Torque Off (STO) to ensure safe operation.
The Bosch Rexroth range of variable frequency drives provides high-quality products that are easy to use and set up, with a range of features that allow you to quickly programme your application’s exact AC electric motor speed control parameters.
With a detachable control interface that can be mounted on the forward door of the electrical control panel, users have simple and easy access to the unit’s potentiometer, stop/start control buttons and display screen.
This means quick parameter settings access and optimising, intuitive diagnosis, and other functions. The detachability of the interface of these variable frequency drives allows operators to quickly configure multiple motor drives by copying and transferring parameters between each VFD using the panel’s memory and copy function in installations.
This is also useful for data processing and in the case of restoring the settings of an older VFD.
Additional braking resistors are available for applications where the controlled electric motor is required to stop instantly, dissipating the voltage produced via electromotive force.
Interface, including Sercos, PROFINET, EtherCAT, EtherNet/IP and Modbus TCP.
