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.

In a barn manure scraper, the motor is part of a drive unit that works very slowly but with very high pulling force. For a correct selection, before the motor power, the output spe... More Details
There is no single "seed cleaner motor" in a seed cleaning and grading machine; the machine consists of several motors, each carrying a different load: the drive that shakes the si... More Details
In a purifier (semolina cleaning machine), motor selection depends on how the machine shakes its sieve box. If the sieve box is driven by an eccentric shaft and a belt, a standard ... More Details
In a plansifter the sieve box does not rotate; it performs a circular oscillation in the horizontal plane, and this motion is produced by an eccentric counterweight turned by the m... More Details
When a packaging conveyor stops and starts dozens or even hundreds of times an hour, the deciding factor in motor selection is not the nameplate power but the heat that builds up i... More Details
Motor selection for a washed food conveyor starts with how much water the motor will be exposed to and by which cleaning method. A standard three-phase motor with IP55 protection c... More Details
On a low-speed conveyor, the choice between a 4-pole and a 6-pole motor does not change the torque that pulls the belt at the gearbox output; for the same power and the same drum s... More Details
Motor selection for an inclined conveyor differs from a horizontal belt in two respects: the power needed to lift the material is added to the calculation, and an arrangement is ne... More Details
Motor selection for a rotary drum screen starts with the speed at which the drum must turn; the gearbox ratio is calculated backwards from that speed. Drum speed is kept at a certa... More Details
Before choosing the motor for a crate conveyor, two things need to be clear: how many crates must pass per hour, and whether stopping of the line is to be handled by the motor or b... More Details
Selecting a motor for a roller conveyor rests on three questions: at what speed the line will flow, what load the rollers will carry with what friction, and by which route the driv... More Details
On an industrial high-pressure car wash machine, the pump motor is selected from the speed, flow and pressure the pump requires; the machine's appearance or the kW value of the old... More Details
On a hydraulic guillotine shear, the pump motor is selected not for the peak power at the hardest moment of the cut, but for the equivalent (thermal) load over the whole cutting cy... More Details
If a compressor motor cannot start against tank pressure, the cause is usually not the motor's power. The most common causes are a faulty unloader or check valve, low supply voltag... More Details
A long starting time on a large fan usually indicates not that the motor is too small, but that the impeller's inertia is large. The real question is whether the motor's winding an... More Details
In fan drives, a direct-coupled motor is the right choice if the speed the fan needs matches a standard motor speed (about 3,000, 1,500 or 1,000 rpm), if the air moved is clean eno... More Details
On greenhouse and poultry house fans, the propeller speed must be kept, because the propeller diameter and blade angle were chosen for a particular speed: if the speed rises the mo... More Details
The motor of a boiler induced draft fan is selected according to the shaft power at cold start-up, when the fan moves its densest air, the speed the impeller was designed for and t... More Details
In an oven circulation fan, heat reaches the motor in three ways: by conduction through the fan shaft and mounting plate, by radiation from the hot oven casing, and through the war... More Details
To replace a burnt-out motor on an axial fan, fit a motor with the same power, the same number of poles, the same shaft diameter and length, and suitable for the same mounting orie... More Details
