Electric drives

Increasingly, electric drive systems are being used for demanding drive tasks on mobile machines and vehicles. Good reasons for this choice include their high efficiency, flexibility of installation and the possibility of energy recovery. Three-phase so-called ‘asynchronous’ motors are often used in AC systems. These require additional components in order for a number of variables to be measured.

An important parameter for meeting the requirements of manufacturers in terms of:

  • minimum replacement outlay
  • fastest availability of replacement parts
  • demanding temperature profiles and signal tolerances
  • component standards close to those of the automotive industry
  • low space requirements for installation

is the prompt, contact-free measurement of rotational speed (and usually also the direction of rotation) in modern electric drive units such as asynchronous machines. RHEINTACHO rotational speed and direction sensors perform this task to the highest levels of customer satisfaction.

The company has focused on the measurement of rotational speed for over 116 years; this is reflected in the extent to which RHEINTACHO speed sensors exceed the industry standards.
