Single-phase motors

Due to their design and wide range of modifications, twin-strand asynchronous motors are used in many applications. They are manufactured in the same mechanical design as the IEC standard motor series in a gray cast iron housing and can be operated on a single-phase alternating voltage network.

Features

These motors are characterized by their compact design, robustness and versatility. The production in a gray cast iron housing ensures a long service life and high resilience. These motors are available in different thermal classes and offer options to adapt to specific requirements. Thanks to their two-strand asynchronous technology, they offer reliable performance and high efficiency. The easy integration into existing systems and the availability of many modifications make them particularly flexible.

Applications

Commonly used in household appliances such as washing machines, refrigerators, and air conditioners, they are frequently found in small industrial machines, pumps, and compressors. Their ease of installation and maintenance also makes them ideal for use in smaller businesses and workshops.

Our range of services

Type series EB21R / EB

  • Single-phase asynchronous motors with operating capacitor
  • The tightening torque of approx. 0.4 MN is sufficient for most applications (e.g. fan drives)


Type series EB21RW / EB2

  • Single-phase asynchronous motors with operating capacitor and resistance rotor
  • The relative starting torque MA/MN is increased to approximately twice the value compared to the EB21R / EB20R series (e.g. used as a concrete mixer drive)

Type series ED21R / ED

  • Single-phase asynchronous motors with operating and starting capacitor
  • This modification combines the advantages of motors with operating capacitors (high performance, efficiency and power factor) with the advantages of starting capacitor motors (high starting torque) and is therefore also suitable for drives with larger counter torques (e.g. pump starting against pressure, compressors, elevators ). The starting capacitor is switched off via switch-off electronics.
