6 7. Warranty Page 6/8 8. Handling 8-1 Low molecule silicon compound, which is included in silicon products, may cause electrical failure. Verify sufficiently when you use silicon products. 8-2 Verify sufficiently that adhesives or seals do not outgas corrosive gases that harm the motor. Cyano adhesive or sulfur gases will cause the motor failure. Also, if an adhesive is used to install the motor, ensure the adhesive does not flow into motor (especially bearing part.) 8-3 Ambient temperature and humidity during motor operation affect performance and product life. Do not store motor in locations subject to high temperatures and high humidity or in corrosive gas environment. Below are recommended storage conditions. Temperature: 5 C ~ +35 C, humidity: 30% ~ 90%. 9. Critical characteristics 10. Others 10-1 Whatever item not stated in this specification will not be guaranteed Do not subject the motor under locked condition for long hours Do not exert pressure by pushing the current terminals towards the direction of the internal motor Out-going test data will be attached (n-35) for Loaded rotation Loaded current Lock current (Starting current) Starting voltage 10-5 Recommended Reflow profile Reflow specification 245 Peak temperature: Rate of temperatuer rise: 1~4 /sec Rate of temperatuer rise: 2~4 /sec 120 Pre-heat time: 70±20sec Above 220 holding time: 30±10sec
