Definitions

  • Blenders in the current state of the art, use universal motors.
  • the universal single phase motor is a type of motor that can operate both with direct current and with alternating current; with some modifications it has a constitution similar to a direct current series motor.
  • the use of the universal single-phase AC motor is widely used in small domestic and industrial blenders; It is characterized by its high rotation and small size; works similar to a direct current motor; The motor maintains the same direction of rotation even when the direction of the power supply is reversed. It has disadvantages such as lower power in alternating current than in direct current; greater brush distortion when operating on AC, requiring periodic maintenance in short periods of time. Its disadvantage is the high noise level, reaching levels above the tolerance limit of human comfort; very close to or above the limits set by occupational health and technical standards.
  • the engine speed cannot be easily controlled as it is totally dependent on the size of the load compared to the size of the engine. If the load is too large for the engine size, the rotation is too slow; If the load is light compared to the engine, the rotation is much faster; has no constant rotation impairing the uniform grinding of processed foods.
  • there is a direct current shunt motor on the market characterized by the rotation that remains constant due to the load characteristics of the armature and the coil, connected in parallel. The speed of the shunt motor can be controlled.
  • the engine's ability to maintain constant, high speed regardless of load changes is due to the field circuit and armature characteristics.
  • the load change is due to the texture of the processed foods; it's inevitable.
  • the "Building Blender Arrangement" described in this report is characterized by the replacement of the "universal motor” with a shunt type direct current motor to achieve a blender with a blade rotation of over 3,600 rpm, AC powered and driven by a direct current (DC) motor, the motor being powered by a single source, with the field and armature circuit connected in parallel, Shunt type.
  • DC direct current
  • the direct current motor known as the "compound” motor has two field windings. One is a “shunt” field connected in parallel with the armature, the other is a “series” field that is connected in series with the armature.
  • the shunt field gives this type of motor the advantage of constant rotation of a regular shunt motor as described above in this report.
  • the serial field gives you the advantage of being able to develop great torque when the engine is started under a heavy load. It can be said that the composite engine has both characteristics of the shunt and series engines. Because the compound engine contains the same characteristics as the Shunt engine, the present patent application also claims the replacement of the universal motor used in the blenders with the compound engine.

Abstract

L'invention concerne un agencement structural pour mixeur, permettant d'obtenir une rotation constante, avec rotation supérieure à 3600 rpm des lames du mixeur, indépendamment de la texture des aliments triturés, et de réduire le niveau de bruit par remplacement du moteur à courant alternatif (CA) par un moteur à courant continu (CC), alimenté par une source unique, avec un circuit de champ et une armature connectés en parallèle, comme dans les moteurs de type "shunt" et les moteurs de type "compound".
