The Optimal Reactor Solution for High Frequency Motor Protection

High Frequency Motor Protection:
Harmful square waves, voltage spikes, and harmonic distortion are filtered from the inverter output, reducing motor heating, wear, and winding stress, providing critical motor protection. With the rise of high frequency/ high speed permanent magnet motors the need for higher frequency reactors has increased. CTM RHF reactors are designed to meet this rising need without requiring costly derates that negatively effect system size, efficiency, and cost.

Stop Rewinding Motors:
CTM RHF reactors reduce harmful voltage spikes and insulation stress. RHF reactors lessen harmonic current distortion, thereby minimizing unnecessary motor heating. By reducing winding stress and motor heat (two primary causes of motor winding failure), motor winding breakdown and failure is greatly reduced, minimizing the need to constantly rewind motors.

Extended System Life and Reliability:
CTM RHF reactors reduce voltage stress and excess heat not just for the motor, but for all other load side components, greatly extending the life and reliability of the entire system.

Inductor Efficiency:
CTM Magnetics patented inductor technology enables highly efficient reactor designs for high frequency applications.

Power Density:
Innovative packaging and cooling systems, combined with highly efficient inductors enable unparalleled power density.

Liquid Cooling:
CTM Magnetics patented liquid cooled technology enables higher thermal efficiency, power density, and performance. With liquid cooling, 97% of the reactor heat is captured by the coolant with only 3% released to ambient. This reduces the need for additional cooling and allows for more flexibility in locating reactors near temperature sensitive equipment.

Military Grade Shock & Vibration:
CTM liquid cooled RHF reactors have been tested and passed rigorous explosive and extreme shock & vibe military testing. RHF liquid cooled reactors are the optimal choice for mobile, marine, and military applications.
