GAMAK was founded in 1961 to overcome the shortage of domestic products in the field of “Electric Motor”, which is one of the most important products needed by the Turkish industry for manufacturing. In a short time, we started to produce the first electric motors of Turkish origin. We created an alternative that eliminated the problems associated with the cost, spare parts supply and price by the use of imported motors. We have been appreciated for our quality. We have continued to grow and develop day by day. In half a century, we have become one of the leading electric motor manufacturers...

As one of the few companies in the world that can produce its own wire, we use wires that we thin between 2 mm - 0.2 mm for our products. In our facility where we have one of the few laboratories in Europe, we produce the highest standard products with maximum efficiency. On one hand, we produce motors with high efficiency (IE2 - IE3), on the other hand, we create the infrastructure required for the production of new generation, efficient motors (IE4) with our R&D investments. Thanks to this potential, we manage the production in a fast, dynamic and flexible fashion. With our ability to produce...

TECHNICAL DATA TECHNICAL INFORMATION

This catalog is prepared to give necessary information on the mechanical and electrical characteristics of 3-phase, cage rotor, fully closed, asynchronous motors manufactured for general use in the industry in accordance with the recommendations of the Turkish Standards Institute “TS” and the International Electrotechnical Commission “IEC”. Frame, Bearing Carrier Covers and Flanges The materials used in the motor bodies, bearing carrier covers and flanges are given in the following table according to their size. GAMAK asynchronous motors are designed, manufactured and controlled in accordance...

TECHNICAL DATA MECHANICAL CONSTRUCTION Note: This standard does not cover the special protection degrees required by machines that are intended to be operated in explosive environments and extraordinary operating conditions such as moisture, corrosive vapors, insects and fungi. GAMAK electric motors are manufactured in accordance with IP 55 protection degree to be able to operate in dusty and humid environments. For this reason, motors can be put into operation in a covered outdoor environment without the need to take any special precautions against mild atmospheric conditions. Motors should...

HORIZONTAL SHAFT Pulling Shaft / Down Force Down VERTICAL SHAFT In our standard production, the shaft end of the motors is single-sided and is fitted with an appropriate wedge (TS EN 50 347 / IEC 60 072-1). In addition, a thread in accordance with DIN 332-2 shape “D” is tapped on the shaft end. Upon request, motors can be manufactured with shaft ends on both sides. The shaft end runout, the concentricity of the flange step and the perpendicularity of the surface are within the normal class limits specified in TS EN 50 347 / IEC 60 072-1. Upon request, manufacturing can also be made within the...
