Russian manufacturer, supplier of electrical equipment VEMZ (Vladimir Electric Motor Plant) He started to create a new generation of electric motors with high energy efficiency. One of the powerful factors of energy saving and, consequently, saving fuel resources and, above all, increasing the level of safety, is the integration of fire-resistant electric motors. In recent years, the company VEMZ designed, has produced and delivered to customers thousands of fire-resistant electric motors of the 5AMP315 series.
A large scientific center of the company, has a powerful testing center for electric machines. It has a unique technical potential for conducting tests for compliance with technical requirements and calculated data of electromagnetic and thermal parameters, for resistance to climatic and mechanical influences, for compliance with the degree of protection. At the same time, the company's production base allows us to manufacture not only serial products in the form of electric machines for various fields of application, but also piece-by-piece production of unique electric motors. The availability of the necessary equipment for all technological conversions and highly qualified personnel is a guarantee that any idea of the customer will be implemented in metal.
Fire-resistant three-phase asynchronous electric motors of the 5AMP315 series with a short-circuited rotor, They are designed to drive fans for the main ventilation of stations and subway tunnels. The engines are available with capacities of 45 and 55 kW, with a rotation speed of 600 rpm. The motors have an insulation system of heat resistance class "H", platinum thermal temperature converters TS034–100 P with a linear characteristic of resistance dependence, sensors for temperature protection of the winding built-in for temperature control of bearings. One of the main features of the engine is the ability to withstand the smoke extraction mode – 1 hour of operation at a temperature of 250 ° C.
