AC tachogenerator and DC tachogenerator (explosion-proof structure tachogenerator with pressure-resistant explosion-proof specifications)

The octopus generator is widely used as a speed control detector for various industrial machinery engines, including vehicles and ships.

Combining a permanent magnet excited rotor with protruding poles and a stator equipped with armature windings, we manufacture various detectors for speed detection, such as a direct current speed motor with permanent magnet excitation, functioning as an alternating current speed generator that detects voltage and frequency proportional to the rotational speed applied to the rotor from the stator side. 【Applications】Assembly products, built-in, semi-built-in 【Capacity】Output: 1VA to 5VA (10W, 30W) 【Features】 ■ No excitation power supply is required due to permanent magnet excitation ■ There are no sliding parts such as brushes or slip rings, reducing maintenance and increasing reliability ■ As a multipole machine, it can control frequency at low speeds with a large frequency relative to rotational speed ■ The change in generated voltage due to temperature variations (temperature drift) is small ■ High precision detection is possible if a frequency-based detection method is employed ■ Good linearity: general specification: 2%, high precision: 0.5% to 1%
