Industrial Electric Motors — HEM Motor

In industry: pumps, fans, compressors and conveyors; in construction: crushing-screening plants and concrete batching plants; in agriculture: irrigation and feed machinery; plus food, textile, plastics and recycling lines. In short, behind every rotating machine there is an electric motor.

Power is chosen from the driven machine's shaft demand and starting load; speed from the rpm the machine needs. Common asynchronous speeds are 3000, 1500 and 1000 rpm (2-4-6 pole). An exaggerated safety margin wastes energy, while borderline sizing causes overheating. Tell us your application and we will pin down the right power-speed combination together.

AC motors run on alternating current, DC motors on direct current. Within the AC family, synchronous motors rotate exactly at line frequency and serve special applications, while asynchronous (induction) motors rotate with a small slip and are the industrial standard thanks to their simple, rugged construction. Our production focuses on three-phase asynchronous motors, which have the widest field of use.

As the manufacturer we supply bearings, fans, fan covers, terminal boxes and windings from our own stock. Most parts ship the same day from our warehouse in Turkey. Send us the serial number on the motor nameplate and we will identify and dispatch the correct part quickly.

The main causes of overheating are undersized motors, blocked ventilation, supply imbalance and overload. Select the correct power for the duty, keep the fan cover and cooling fins clean, and use thermal overload or PTC protection. On applications with frequent starts, a variable frequency drive also keeps winding temperature under control.

Three-phase motors run on 380 V industrial supply, deliver balanced torque at higher powers and are the industry standard. Single-phase motors run on 220 V domestic supply and usually serve small pumps, compressors and workshop equipment up to about 2.2 kW. If your facility has a three-phase line, a three-phase motor of the same power will run more efficiently and last longer.

Evaluate in order: required power (kW) and speed, mounting arrangement (foot/flange), efficiency class, protection class (IP) and the operating environment. Special conditions such as frequent starts, high inertia or drive operation affect the choice. When in doubt, share your application details and we, as the manufacturer, will recommend the right model.

Yes. The IE3 and IE4 motors we manufacture do the same work with less electricity than older generations. In a 24/7 plant the yearly saving per motor can cover a large part of its price. Send us the nameplate data of your current motors and we will prepare a concrete savings calculation.

As the IE level defined in IEC 60034-30 rises, more of the energy a motor draws is converted into useful work. IE4 (super premium) and IE5 (ultra premium) motors cut losses noticeably compared with IE2-IE3 models. On motors running long hours daily, even a few percent of extra efficiency turns into substantial yearly savings, so the price difference typically pays for itself quickly.

An asynchronous (induction) motor has no brushes or commutator on its rotor; this simple construction means few failures, easy maintenance and low cost. It can run direct-on-line or with a drive and withstands harsh environments. That is why it is the most widely used industrial motor type and the core of our production programme.
