The Kacperek company has a wide range of electric motors. A huge warehouse of electric motors allows for immediate order fulfillment.
We offer single-phase and three-phase electric motors in flange and foot design, as well as many others, including:
- electric motors with power from 0.06kW to 30kW kilowatts (higher powers are also available on request);
- asynchronous and synchronous electric motors;
- single-phase, three-phase, direct current electric motors;
- foot and / or flange mounted electric motors;
- electric motors with a brake. The electric motor with a brake is designed to work in devices where independent motor movement without voltage is not allowed;
- explosion-proof electric motors;
- stainless, anti-corrosion electric motors;
- water resistant electric motors, high dustiness, up to IP69K
- marine electric motors for high / low temperature operation;
- multi-speed electric motors;
- electric motors with special power in accordance with the standards in force in other countries;
- electric motors with built-in encoder and inverter;
- electric motors for fans, circular saws, pumps, other devices;
- electric motors with additional cooling. External cooling is nothing more than an external fan, with independent power supply, which is built on the motor for better heat dissipation. In most cases, they are used when the motor is operated with an inverter, when at low revolutions of the own fan, the cooling efficiency is low and the motor starts to heat up. Overheating the engine can damage it. External cooling is most often used when the engine speed during continuous or long-term operation is below 700 [1 / min]. It is not a hard line. It all depends on the environmental conditions, temperature, humidity, dustiness, building conditions (air circulation) and load. In some special cases, even 8-pole motors (about 700 [1 / min]) are equipped with an external fan. It all depends on the temperature of the engine during operation.
Our offer includes forced cooling fan motors, which we can fix with any engine. They have 230V or 400V power supply as standard (other voltages on request). Please note that when working with the inverter, external cooling must be connected independently.
We also offer hydraulic motors.
Basic parameters of the engines we offer:
Insulation class
In all presented engines, class F insulation is used (operating temperature up to 155 ° C).
All motors with non-fractional power have temperature sensors built into the windings which, when using the correct electromagnetic switch, allows the motor to be switched off automatically if the permissible winding temperature is exceeded.
Motors of size 160 and larger are equipped with a PTC sensor
The insulation system of these motors allows them to be powered by a current frequency converter (inverter).
Level of security
The motors offered have an IP55 degree of protection according to EN 60034, which means that the motors are resistant to the penetration of dust in quantities that interfere with their work and the flow of water from any direction.
Engine construction
160 mechanical motors are in aluminum housings. In turn, the motors from the mechanical size 180 are made in a cast iron housing.
The bodies have such a construction that allows the configuration of the motor with a terminal box located on the top, on the right or on the left. As standard, the motors are delivered with a terminal box at the top.
Łożyska
Motors up to the mechanical size 180 are equipped with indoor bearings (ZZ or 2RS) and require no maintenance. In contrast, motors from the size of the mech. 200 are equipped with grease nipples. The lubricant should be topped up in accordance with the attached technical documentation.
Cooling
In the standard engine, the cooling function is performed by a fan mounted on the shaft and covered by a perforated cover. Due to the fact that the fan is mounted directly on the motor shaft, the cooling efficiency is closely related to the rotational speed of the shaft.
Engines designed to work with inverters whose rotational speeds will be lowered below 700 rev / min should be equipped with an independent cooling system (so-called external cooling). Thanks to this solution, the engine cooling intensity is constant and independent of its rotational speed.
Efficiency of IE1, IE2, IE3
The efficiency of the electric motor is the ratio of the mechanical power given to the motor shaft to the electric power consumed by the motor. Electricity that is not converted into mechanical energy causes losses. To reduce these losses and increase the efficiency of the engine, its design and materials are optimized.
In European Union countries, legal regulations regarding the efficiency of low-voltage electric motors have been introduced. In 2009, the European Commission published the (EU) Regulation 640 / 2009, also known as EU MEPS (Minimal Efficiency Performance Standard). The regulation established:
- the subject and scope of the engines covered by the regulations,
- levels and efficiency classes (IE1, IE2, IE3, IE4),
- the method of determining efficiency on the rating plates,
- the timetable for implementing the directive.
Exclusions:
- engines equipped with a variable speed controller (with inverter),
- braked engines,
- explosion-proof motors,
- 700rpm engines,
- engines designed to work:
• in full immersion in liquid,
• at altitudes above 4000m above sea level,
• at an ambient temperature above 60 ° C,
• at ambient temperatures below -30 ° C,
• other according to the regulation.
