In a vertical shaft impact crusher (VSI), the rotor is driven by belt either by a single motor or by two motors placed on either side of the crusher. In a single-motor arrangement,... More Details

The electric motor of a cone crusher usually drives the crusher's countershaft (pinion shaft) by V-belt; the compatibility of a spare motor is therefore checked starting from this ... More Details

On a diamond wire saw, the main motor sets the cutting speed of the wire by turning the drive wheel. That is why three questions are answered together when choosing the motor: how ... More Details

When replacing the motor on a pillar drill, the easiest route is to choose a motor with the same power, the same number of poles and the same shaft diameter as the old one and to m... More Details

The main motor of a universal lathe is chosen to match the power and speed on the lathe's nameplate, preferably with the same number of poles and the same mounting arrangement. All... More Details

When you replace the motor on a metal band saw, the way to keep the blade speed unchanged is to choose the new motor with the same number of poles (usually 4 poles, the 1,500 rpm c... More Details

A single fixed speed is not enough on a wood lathe: a large-diameter bowl blank must turn slowly, while a thin pen or spindle job must turn fast. This wide speed range used to be o... More Details

On a thickness planer, what determines main motor power is the volume of chips removed in a pass: the amount of wood removed per minute, obtained by multiplying board width, depth ... More Details

What determines motor selection for a surface planer is the speed at which the cutter block (cutter head) must turn and how that speed is obtained from the motor by belt. On most p... More Details

In a food mixing tank, the two quantities that determine motor power are the product's consistency (viscosity) and the speed of the agitator shaft; a motor chosen without consideri... More Details

What strains the pump motor on a bottle washing machine is often not the electrical load but the motor's surroundings: steam rising from hot caustic solution, label pulp stripped o... More Details

When selecting a circulation pump motor for a pasteuriser, first separate which circuit the pump works in: is it the hygienic pump carrying the product, or the service-circuit pump... More Details

When choosing a motor for a food slicing machine, the first question is not power but the speed at which the blade turns and how that speed reaches the blade from the motor. If the... More Details

Two things determine motor power in a tomato paste machine (pulper/passatore): how thick and fibrous the incoming product is, and the hole diameter of the screen through which the ... More Details

On a nut roasting machine, the drum motor and the fan motor are two motors that do two separate jobs on the same machine and see very different loads. The drum motor slowly turns a... More Details

For an industrial meat mincer, motor selection starts with the plate (perforated disc) size and the amount of meat processed per day, but what makes a replacement successful is rea... More Details

Replacing the motor of a planetary mixer depends less on the motor's power than on reading the gearbox and the mixer's duty cycle correctly. In a planetary mixer the motor drives a... More Details

When selecting the motor for a metal shredder, the real deciding factor is not the type of material being shredded but the path by which the impact reaches the motor. On a low-spee... More Details

On a plastic raw material mixer, the motor and gearbox are selected as a package: the gearbox determines the speed and torque that the mixer shaft needs, and the motor must have en... More Details

What strains the motor of an agglomerator is not a single load but a load curve that repeats with every batch: it starts light with an empty drum, the current climbs as the film he... More Details
