Frequently asked questions

Find clear answers to common questions and past inquiries, Clear answers to common curiosities.

How do you choose motors for crushing and screening plants?

In crushing-screening duty a motor must withstand shock loads, heavy dust and continuous operation. Besides the power the crusher requires, look for high starting torque, IP55 protection and a cast-iron frame. Gearmotor solutions are preferred for conveyor, screen and feeder drives. Share your plant layout and we will size the right power and speed together.

Will HEM Motor reduce my energy costs?

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.

How do ordering, delivery and commissioning work?

Once your requirement is clear, in-stock motors ship the same day; delivery across Turkey usually takes 1-3 business days. Our technical team supports installation by phone or on site for mounting type (B3, B5, B14, B35...) and terminal connections. At commissioning we recommend torque, current and rotation checks.

Are the motors protected against dust and water?

Protection level is stated by the IP code. Our standard production is IP55: complete dust protection plus resistance to water jets from any direction, suitable for outdoor, humid and dusty environments. For heavier duties such as washdown areas, IP56/IP65 options can be manufactured.

In which fields are HEM Motor products preferred?

Our motors are widely used in pump and booster sets, fan-ventilation systems, compressors, conveyor lines, crushing-screening plants, concrete batching plants, agricultural and food machinery, and recycling lines. With a manufacturing range from 0.55 kW to 355 kW we supply businesses of every scale, from small workshops to heavy industry.

How are motor power and speed determined?

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.

What is the difference between single-phase and three-phase motors?

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.

How does spare part supply work?

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.

What are the differences between AC, DC, synchronous and asynchronous motors?

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.

How often should an electric motor be serviced?

As a rule of thumb, check bearings and grease every 3-6 months and carry out general maintenance yearly, adjusting for operating hours and environment. Shorten the intervals in dusty or humid conditions. Regular vibration, temperature and insulation measurements catch faults early and significantly extend motor life.
