Russian manufacturer and supplier of electrical equipment VEMZ (Vladimir Electric Motor Plant) He started to create a new generation of crane electric motors of the 5AC, 5AT and 5ACH series of high performance. Therefore, to increase the productivity of work processes in the construction sector, an important component is the integration of crane electric motors of the 5AC, 5AT, 5ACH series. Accordingly, in recent years, the company VEMZ She designed, produced and handed over to customers thousands of modifications of crane electric motors of the 5AC, 5AT, 5ACH series.
The large scientific center of the company has a powerful testing center for electric machines, while having a unique technical potential for testing 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.
Three-phase asynchronous two-speed electric motors with a short-circuited rotor of the 5AC, 5AT and 5ACH series are designed to drive lifting mechanisms and movement of cranes for various purposes. The power of crane electric motors varies from 5.5 to 37 kW, the speed ratio is 3:1 and 4:1. The drives of these series have two independent windings on the stator, which in turn allows you to obtain favorable mechanical characteristics at different speeds. The overload capacity is more than 2.5. The motors are designed to operate from a 50 Hz AC network with a voltage of 380 V. Climatic version U1. Degree of protection – IP54.
