Development of synchronous motors and generators according to the Customer's requirements

The high-speed electric reversible machine VELMA is designed to work as part of the test bench equipment. The VELMA product is connected to the stand load unit and during testing provides the load of the tested product according to the specified program. VELMA is a synchronous electric machine excited by high-coercive permanent magnets. The product is designed to operate both in the mode of converting mechanical energy into electrical energy (generator mode) and in the mode for converting electrical energy into mechanical energy of rotation (motor mode). VELMA is capable of operating in the “starter-generator” mode. In the starter mode, the electric generator is started in the motor mode for preliminary unwinding of the gas turbine engine. In this mode, the frequency converter is powered from an external industrial electrical network or from a high-voltage storage battery. When switching to the generator mode, it switches to power from an electric generator and generates electricity of a given type and quality at the output of the product. The product is controlled from the operator panel located on the control unit or via a digital communication channel (RS-485 ModBus RTU). VELMA can be adapted. for your tasks with a high degree of flexibility: 1) by power: from 5 kW to 2.5 mW 2) by frequency of revolutions per minute: from 5,000 to 110,000 rpm types of bearing arrangements: ЛГП – petal gas-dynamic bearings ГДП – hydrodynamic bearings AMP – active magnetic suspension ШП – ball bearings (rolling bearings) Preparation for serial production is possible, including obtaining all necessary licenses and certificates and passing tests, and directly organizing serial production.
