what we do
Our Solutions
Jet Fans/ Tunnel Fans
Jet Fans provide excellent ventilation for environments where circulating fresh air is a challenge, including multi-storey car parks and underground garages.
A good tunnel fan ventilation is a fundamental element for a proper air ventilation, ensuring the extraction of toxic gases and the control of suspended particles for the full safety of this environment.
Tunnel jet fans are for installation in large road, metro and train tunnels, where the transport and removal of exhaust gases as well as ventilation is essential for the comfort and safety of users, cars or rolling stock. In case of fires, the jet fans double-function as invaluable aids for the fire-fighting services and help contain and control the spread of smoke.
From individual applications up to large-scale infrastructure projects in industry, the unparalleled efficiency, compactness and superior performance of PM motors make them the obvious choice.
PM motors are suitable for applications such as material handling, HVAC, water and wastewater, automotive, food processing, textiles – to name just a few. PM motors are not limited to conventional applications, but excel in other demanding use cases, especially where constant torque is required or high power density is a decisive factor.
The wide field of applications that can be addressed includes the following, for example: Pumps, Fans, Blowers, Compressors, Cranes, Conveyor belts, Extruders, Mixers.
advantages of Permanent Magnet Motors
Simple Structure, High Reliability, Maintenance-Free
The advantages of a permanent magnet synchronous motor (PMSM) compared to an asynchronous motor include smaller size, lighter weight, lower losses, higher efficiency, higher torque-to-inertia ratio, measurable rotor parameters, and good controllability. Its vector control system can achieve high precision, high dynamic performance, and a wide range of speed or position control, making it widely used in various energy-efficient, high-efficiency, high-precision control, and low-noise motor applications.
High Efficiency, Low Energy Consumption
After embedding permanent magnets on the rotor of a permanent magnet synchronous motor, the rotor’s magnetic field is established by the permanent magnets. During normal operation, the rotor synchronously rotates with the stator’s magnetic field, resulting in no induced rotor current. This eliminates rotor resistance losses, which alone can improve motor efficiency by 5-10%. Due to the absence of induced rotor current excitation in permanent magnet motors, the stator winding may behave as a purely resistive load, resulting in a power factor close to 1 for the motor.
Comparison of PM motor and Asynchronous motor
