Integrated Motor-Compressor System
Emission free advanced centrifugal compressor technology with an electric motor driver in a single, completely sealed casing –up to 20 MW and up to 18,000 rpm
The system is driven by high-speed motor and high-frequency drive technology. The pressurized, induction motor includes a laminated rotor with a squirrel cage—a design proven by more than four million operating hours in industry-wide applications.
With Active Magnetic Bearings (AMB) technology, the rotor is levitated by a control system that precisely regulates the rotor spacing to avoid all parts contact and friction. This eliminates the need for lubricant thereby solving the problem of leak-prone lube oil systems used with conventional bearings. The AMB design maintains rotor levitation during starts, normal operation, and stops including emergency shutdowns. Ball bearing back-up allows the machine to stop without damage.
The drive is highly efficient over a very wide operating range, with the same hardware capable of driving the motor at low speeds and all the way up to 300 Hz, then helping reduce power consumption.
