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.

When you look at a motor's nameplate, you easily read its power, speed, current and efficiency class; but especially on a motor built to the NEMA standard, the single letter next t... More Details
When you run an IE5 synchronous reluctance motor at very high speed continuously, for example on a turbo blower, a high-speed compressor or a test bench, the most stressed part is ... More Details
When commissioning an IE4 super premium efficiency motor in a dusty environment, most engineers focus on the efficiency class, winding quality and bearing life; but they rarely loo... More Details
When moving a large cast iron asynchronous motor from the factory to the field, one thing is often overlooked: throughout the long transport period when the motor is not running an... More Details
In a crusher (stone-crushing) plant, the main crusher motor is the heart of the entire line. When this motor stops, not only the crusher but the whole feeder, conveyor and screeni... More Details
On an IE3 motor running in high-power and critical applications, measuring winding and bearing temperature at only one point is not sufficient. Different regions of the motor heat... More Details
One of the most insidious faults of an asynchronous motor is an earth (frame) leakage. When the winding insulation degrades over time due to moisture, heat, vibration or contamina... More Details
When a machine needs to run at two different speeds, the first solution that comes to mind is a variable frequency drive (VFD). However, if only two fixed speeds are sufficient an... More Details
In pump, fan and blower applications, the most effective way to control flow, pressure and energy consumption is to adjust the motor speed precisely. In most cases a variable freq... More Details
High-efficiency electric motors stand out for their long life and low fault rate in continuously running pump, fan, compressor and process lines. But the most critical maintenance ... More Details
Most three-phase electric motors have a dual-voltage construction that allows them to run at two different voltages by re-arranging the bridges in the terminal box. A motor whose n... More Details
IE5 synchronous reluctance (SynRM) motors — with their magnet-free rotor, high efficiency and drive-coupled operation — represent the ultra premium efficiency class of the future. ... More Details
Large IE4 super premium motors running in continuous processes, pump-fan-compressor lines and critical production plants face the risk that a stator winding fault can destroy the e... More Details
Cast iron framed brake motors are used in conveyors, cranes, hoists and vertical drives where the load must be held safely. They are equipped with a spring-applied electromagnetic ... More Details
Crusher and stone-crushing plants operate not only on hot summer sites but also in cold-climate and arctic regions where winter drops to -40 °C. In crushing-screening plants in Sib... More Details
When selecting a motor in the IE3 efficiency class, only the standard enclosed (TEFC, IP55) frame usually comes to mind. Yet in high-power and special applications, the motor's coo... More Details
How many leads you see when you open the terminal box of an asynchronous motor directly determines what you can do with that motor. In three-phase asynchronous motors, the terminal... More Details
Two-speed (dual-speed) electric motors provide great flexibility in many applications such as fans, pumps, elevators and conveyors by offering two different operating speeds in a s... More Details
The most common assumption in pump, fan and blower motors is that "the higher the IP rating, the better." This is not always true. For a fan motor running indoors in a clean, dry s... More Details
A high-efficiency motor does not merely consume low energy; it also stands out by being quiet, low in vibration and long in bearing life. At the root of these qualities lies a conc... More Details
