Cables for Frequency Inverters and Motors

In modern drive technology, the efficiency of a system depends not only on the quality of the motor or the frequency inverter (VFD), but significantly on the connection between them. SEVA-tec, as an expert in drive solutions, offers specialized connection and control cables precisely tailored to the requirements of electric motors and frequency inverters.

Why special cables for frequency inverters?

Frequency inverters operate with high-frequency pulse width modulation. Without proper shielding, these cables can act like antennas and emit electromagnetic interference (EMI). This affects not only the motor's performance but can also disrupt neighboring electronic components or sensors in industrial environments.

Cables from SEVA-tec are characterized by the following features:

• Optimal EMC shielding: A dense braid of tinned copper wires protects against electromagnetic influences and ensures trouble-free operation according to EMC directives.
• High dielectric strength: The insulation materials are selected to permanently withstand the voltage peaks that occur during inverter operation.
• Mechanical robustness: Whether for fixed installation or flexible use in cable carriers – the cables are oil-resistant, flame-retardant, and extremely durable.

Control cables for precise signal transmission

In addition to power transmission, control cables play a central role. They transmit critical signals for speed control, thermistor sensors (PTC), or encoder feedback to the frequency inverter. Error-free signal transmission is the basic requirement for the precise process control that is standard with SEVA-tec drives.

Conclusion: Safety and efficiency through quality

Those who rely on drive components from SEVA-tec should not compromise on accessories. The use of high-quality, shielded motor connection cables minimizes downtime, protects motor bearings from electrical discharge (EDM), and significantly extends the service life of the entire drivetrain.
