In large-capacity crushers and mills, the drive power required can reach levels that push the practical limits of a single motor. In such cases there are two common approaches: eit... More Details
As IE3 efficient motors move up to larger powers, the high starting current that appears during direct-on-line (DOL) starting becomes a problem. While the classic methods of reduci... More Details
The vast majority of asynchronous motors run with a squirrel-cage (short-circuited bar) rotor; this rotor, in which aluminium or copper bars are joined by short-circuit rings, is a... More Details
A 710 kW class electric motor sits far above the powers most industrial plants are used to, in the ultra-large-power region. A motor of this size is no longer ordered like a standa... More Details
In pump, fan and blower drives a large share of the noise a motor radiates comes from a single, often overlooked component: the cooling fan behind the motor and the fan cowl that c... More Details
In small workshops, agricultural irrigation points and many domestic applications where a three-phase grid is not available, the power source is single phase. The single-phase moto... More Details
Electric motors run not only in the horizontal (foot-mounted, IM B3) position; they can work in many different positions such as shaft up, shaft down or wall-mounted. But the mount... More Details
IE5 synchronous reluctance motors always run with a frequency drive (VFD), because the synchronous reluctance rotor cannot start directly from the grid. The voltage at the drive ou... More Details
In high-power IE4 motors, the inrush current drawn during direct-on-line (DOL) starting can reach 6 to 8 times the rated current. This high momentary current causes voltage dips on... More Details
In heavy belt-and-pulley drives, the radial load reaching the drive end (DE) of the shaft can push a standard deep-groove ball bearing beyond its rating. In large fans, crushers, r... More Details
In a crusher plant, material is most often carried from the crushers to the screen and stockpile by inclined belt conveyors. These belts can be hundreds of metres long and climb a... More Details
When you want to bolt an IE3 motor to a pump, a gearbox or a machine, the success of the installation is decided as much by the flange type and dimensions as by the construction t... More Details
You don't want a conveyor belt to spill its load when it stops, a crane load to drift downward while suspended in the air, or an automatic door to coast freely as it closes. This ... More Details
The speed of an electric motor is directly determined by the number of poles, and this simple relationship plays a key role in solving many of the drive problems encountered in ind... More Details
A fire pump system is one of the most critical mechanical installations for the life safety of any facility, and the silent hero of this system is often overlooked: the jockey pump... More Details
For every manufacturer exporting machinery or motors to the European Union market, the motor's efficiency class is no longer a choice but a legal requirement. The EU's Ecodesign re... More Details
The most important line of defense protecting an electric motor from burning out is the thermal protection sensors that monitor the winding temperature. When the winding temperatur... More Details
IE5 ultra premium efficient synchronous reluctance motors, while offering the highest efficiency class, are often run in harsh dusty, wet or washdown environments. In these environ... More Details
In IE4 super premium efficient motors operating in humid and outdoor environments, condensation water accumulating inside the frame is a problem that often goes unnoticed yet cause... More Details
In any belt-and-pulley driven system, one of the most critical yet frequently overlooked mechanical components that determines how efficiently and reliably the motor will run is th... More Details
