1.1. YZ series motors are shaded pole motorswith single-phrase and four-pole, and running at the rated voltage/frequency of 220-240V, 50/60Hz or 110-120V, 60Hz. They are widely applied to radiators, evaporators and other refrigeration equipments. 2. The output power is from 5W to 34W, which can be adjustedaccording tothe stack’s length. 3. The insulation class of the motors is B, and the protection class of that is IP42. And we can supply motors with IP44 protection class as per clients' requirement. 4. Motors of output power below 10W have impedance protection, and motors of output powerabove 10W have thermal protectors whose cut-off temperature is 135oC±5oC. 5. The applicable environment temperature of the motors is from -40oC to +50oC. 6. The average working life of the motors is over 20000 hours. 7. We recommend horizontal installationas our standard motorshaveoil bearings. In the meanwhile, we can produce motors with ball bearings according to clients' need. 8. All of the shaded pole motors have attained CE, VDE, Rohs, and CCCcertificates.
