At HEM Motor we do not merely supply electric motors; we manufacture them in our own facility and ship them from stock. An electric motor is the workhorse that turns grid electricity into a rotating shaft to drive your machine, and in this category you benefit both from the engineering know-how of a maker and from the wide stock and quick dispatch of a supplier.
Our portfolio reaches from small workshop powers to the high-power demands of heavy industry. On the efficiency side we cover IE3, IE4 and IE5; on the body side cast iron and lightweight options; and on the drive side different pole counts, all under one roof. Our motors are built with IP55 protection and Class F insulation, with slip near 4% around full load.
Choosing the right motor the first time affects both the initial outlay and years of running electricity cost. If you are unsure which power and speed suit your job, our engineering team advises based on your application.

Summary (TL;DR) A roller screen (disc screen) is the ideal screening solution for sticky, wet and clayey feed where vibrating decks blind and clog; each drive shaft demands low sp... More Details
Summary (TL;DR) 0.12 and 0.18 kW motors are the smallest power class in the range; they are ideal for small automation, dosing, packaging machines and especially as a worm gear re... More Details
Summary (TL;DR) The asynchronous motor equivalent circuit (R1, X1, Xm, R2'/s, X2') mathematically explains motor behavior; torque is directly tied to rotor copper losses and slip.... More Details
Summary (TL;DR) The 2.2 kW electric motor is one of the most stocked and fastest-supplied single power ratings in industry; correct selection starts not with power but with pole c... More Details
Summary (TL;DR) A wall-mounted propeller (axial) fan motor is designed for ventilation that demands high airflow at low pressure; correct selection depends on airflow, blade diame... More Details
Summary (TL;DR) Replacing old or standard-efficiency motors with a high-efficiency motor (IE4 Super Premium, IE5) permanently cuts electricity use and, indirectly, CO2 emissions; ... More Details
Summary (TL;DR) In a glass and ceramic factory, the biggest enemies of electric motors are high hot environment temperature, abrasive dust and non-stop operation; therefore a cast... More Details
Summary (TL;DR) An IE5 synchronous reluctance motor (SynRM) cannot start direct-on-line; it always requires a variable frequency drive (VFD). Motor and drive must therefore be sel... More Details
Summary (TL;DR) Overload capacity and breakdown torque margin determine how much sudden load a motor can absorb while staying in stable operation; when choosing an IE4 motor, this... More Details
Summary (TL;DR) The stator lamination core is built by stacking thin, insulated silicon-steel sheets and press-fitting them into the cast iron frame; the quality of this fit direc... More Details
Summary (TL;DR) A rotary airlock (also called a cellular feeder or vane feeder) is the drive element that sits under the baghouse or cyclone dust collector in crusher and mining p... More Details
Summary (TL;DR) The 75 kW IE3 motor is a general-purpose industrial motor in the high-power class; however, 75 kW sits exactly at the IE4 threshold. From 1 July 2023, under EU Eco... More Details
Summary (TL;DR) The low-frequency hum you hear from an asynchronous motor usually comes not from the bearings but from the stator core; this sound is caused by magnetostriction. O... More Details
Summary (TL;DR) The 0.37 kW motor (about 0.5 HP) is one of the most popular single-power classes in the small-power range; with the right pole and mounting it covers a very wide f... More Details
Summary (TL;DR) Blade type directly drives motor selection: Sirocco (forward-curved) fans have a power curve that keeps rising as flow increases; backward-curved and airfoil blade... More Details
Summary (TL;DR) A soft starter does not save energy during continuous running; it only controls the starting phase by ramping voltage up via thyristors (SCRs) to limit inrush curr... More Details
Summary (TL;DR) RDF/SRF waste-derived fuel preparation plants contain machines with very different load profiles — shredders, screens, separators, fans and conveyors — and each ma... More Details
Summary (TL;DR) The saliency ratio is the heart of a synchronous reluctance motor: the larger the gap between the rotor's d-axis inductance (Ld) and q-axis inductance (Lq), the mo... More Details
Summary (TL;DR) Power factor (cos φ) and efficiency are not the same thing: efficiency classes such as IE3 and IE4 define the motor's active power loss, not cos φ directly. A high... More Details
Summary (TL;DR) The flange spigot (register/rabbet) is the machined diameter ring on a cast iron motor's drive-end shield; it seats the motor concentrically onto the pump, gearbox... More Details
