6. 注意事项
Cautions
● u使用范围相关
Allowable range for use u 1)严格按照规格书的使用条件，不当的使用电压及电流会损害马达性能及寿命，请注意.
Unless it is used in accordance with the specifications, the performance and life may be considerably reduced. Due attention should be paid to the voltage and current ranges for use. ● 2)在马达工作时，请考虑在电路中设计滤噪电路以减小电路噪音.
Use Noise filter circuit to reduce electrical noise when the motor is rotated ● u储存保管
Storage
1)避免置放于高温、高湿或有害气体的环境中.
Avoid storing in high temperature, high humidity or corrosive gas environment. ● 2)保质期
马达内含精密零件含油轴承，其质保有效期为9个月，若马达长期保存超过9个月，马达初始起动
可能不稳定，但会随着轴承内含的油循环系统正常化而正常.
● ● u其它
Others
1)不要将磁体靠近或接触马达,这样会极大地恶化马达性能 .
Do not bring a magnetized object near the motor, which causes deterioration. ● 2)注意在传递和工作环境中,有些粉粒一旦依附在马达磁铁上,将会产生噪音,恶化性能,降低可靠性 .
Due attention must be paid to the handling and working environments because such objects as iron powder if attracted by the motor magnet, will cause noise, characteristic deterioration, thus reducing the reliability. ● 3)请注意,不要将马达靠近高温超过90℃,内含的磁铁会因高温而退磁，将会恶化马达性能.
Do not heat the motor over 90℃, which causes deterioration. ● 4)作用于马达上的力不得超过1.0 kg.f,因会影响马达性能或使其变形 .
Do not press the motor with more than 1.0Kg.f, which may cause the decrease of the performance or the deformation of the motor. ●
