ABB motors (and generators) is a further group of essential electrical appliances about which we would like to talk a bit. The manufacturer from Switzerland has already astonished us with some other devices, and this time is no different. Since we have also reviewed several other groups of ABB electrical appliances, you may want to familiarize with them, too. Read one of the next articles to become familiar with some other ABB devices:
Now we want to give heed to the ABB motors that are available in a great number of model types. We could sort ABB motors in groups by the power output, supported standards, and domains of usage. According to the main website, ABB motors exist only in low-voltage and high-voltage variants. This seems to be a different approach if we compare it with other sets of ABB devices, as other products have also middle-voltage modifications. But ABB does have middle-range motors. As for the supported standards, low- and high-voltage ABB motors get such merit badges as IP, IK, IEC, NEMA, EN, etc. There are plenty of applicable standards, and they vary depending on the country. Consequently, ABB has to make motors that conform with all of them. You can be at least sure that most ABB motors have good-enough shield against water ingression and impacts, not to mention protection from vibrations. In respect of domains of usage, ABB makes motors for six of them, including mining, marine, power, water, food-and-beverage, and petrochemical industries. Now let’s dive into technology and learn in greater details some ABB motors.
IEC Low Voltage Motors from ABB
The group counts only four different types of motors. The company itself separates IEC low-voltage motors into sub-groups in relation to the technology used in them. Motors for special applications draw our attention because they seem to be the most advanced IEC low-voltage devices. ABB offers mining, marine, smoke-extraction, and brake motors in the sub-group of special applications devices.
Example: the ABB motors for fire protection systems. Such a motor is typically used during emergency situation to suck air using the ventilation in the building.
Main Specifications of ABB Smoke Extraction Motors:
- Horizontal/vertical installation;
- Support for EN 12101-3 standard;
- Support for four protection classes;
- 75 up to 500kW output;
- 2 up 12 poles (depending on the IEC size);
- Support for voltage up to 690V;
- Cast-iron frame.
Synchronous Motors from ABB
This group of ABB motors is definitely much bigger – there are thirteen types of devices. The client can find synchronous motors for general installations, and many others for specific types of applications. This time we are mostly interested in synchronous motors for water and waste-water applications. These devices are improved for pumps. They provide very high torque at low-to-medium speeds. We also like the fact that we can choose a cooling method for our ABB synchronous motor, such air-to-water closed circuit cooling or open-air cooling, etc.
Example: the ABB synchronous motors for water pumps.
The list of specifications:
- Compact and light design;
- Horizontal/vertical installation;
- Solid rotors with incorporated four to six poles;
- Modular design to allow further optimizations;
- Different cooling options;
- Low-to-high protection levels (IP23, IP44, IP54, and IP55);
- Additional NEMA protection classes.
Traction Motors from ABB
ABB makes traction motors, as the nomination suggests, for trains. These motors exist in two modifications, either modular or frameless one. Traction motors from ABB are effective in using electricity. In order to make the motors competitive in this domain, ABB offers a possibility to order a specifically made traction motor for a certain application.
Example: the ABB traction motors.
The Main Specifications of ABB Traction Motors:
- Robust structure;
- Four cooling options (close/open passive ventilation, forced ventilation, water cooling);
- Copper or aluminium rotors;
- Great protection against vibrations;
- Built-in stator insulation system;
- Specific modifications can be made to respond to specific conditions.
High-Voltage Induction Motors from ABB
The main motors in this line are HXR and NXR ones. They employ simple rib cooling. Other than these, we can get slip-ring motors, modular induction motors, and process performance cast-iron motors. The NXR motors are the modern editions of HXR ones. Speaking of which, let’s get to know them better.
Example: the ABB NXR motors for high-voltage applications. The company claims that these motors can be used in many industries thanks to the advanced structure and high efficiency.
The List of Specifications of NXR Motors from ABB:
- Enhanced protection against liquid ingress and dust particles (up to IP66);
- Two up to 12 poles;
- 100 up to 1250kW power output;
- Different combinations of motor enclosures (IC + IP marking);
- Several frame sizes;
- Horizontal installation only.
Motors for Explosive Environments from ABB
The company was able to create several additional groups of motors that are capable to withstand influence of explosive atmosphere. ABB makes motors that have a better-than-usual level of safety – such items are found on the Increased safety motors page. Other pages include dust-ignition proof motors, flameproof motors, and non-sparking motors. The last range of highly protected ABB motors presents pressurized ones.
Example: the ABB dust-ignition proof motors.
The Main Traits of ABB Dust-Ignition Proof Motors:
- The maximal power output equals 7700W;
- Five types of such motors;
- Multiple IEC enclosure sizes;
- 0.55 up to 7700kW power output;
- Conform with multiple international standards;
- Two up to 12 poles;
- Support for voltages between 1kV up to 13.8kV;
- Three ingress protection classes (IP55, IP56, and IP65);
- Support for both horizontal and vertical installations;
Summary on ABB Motors
As you can see, the Switzerland manufacturer strives a lot to produce motors that will comply with all national and international standards. This is a truly hard work, and it seems that ABB was able to handle it. If you have already visited the main website, you may have noticed that ABB has somewhat complicated its motors product range. For example, we can see the same types of motors in different groups, which is a bit perplexing. Nonetheless, knowing that ABB motors are used all over the world, we can be sure that any item is high-quality. And don’t forget about auxiliary components that can be used to further improve ABB motors.
