PRODUCT OVERVIEW
Among series YDT motors, the pole- -and speed-changing 3-phase asynchronousmotor specially matched for the load of fanblowers or pumps is an outgrowth fromseries Y motors.
The series motors are novel in design their rotational speed will decrease by deg-rees of quadratic relation with the increase in the load of fanblowers or pumps, their torque properties: the power of motor is directly proportional to the quadrate of rotational speed Due to it that they can reasonably match the corresponding power according to the complemental requirement of rotational speed, they can save a lot of energy,
therefore may be rated as an ideal dynamic force for the fanblowers of load type they are widely used in metallurgy, mining, textile, dyeing, chemical industry, light industry, architecture, civil facilities and other departments virtues of high efficiency, saving energy, low noise, ittle vibration, fine isolation reliable operation easy maintenance, etc.
Series YDT motors conform to the international standards of IEC, Their main qualifications have reached the advanced standard among the same products both at home and abroad.
This company produces series YDT motors strictly according to the atandards of JB/T8681-1998.
