This standard specifies the technical requirements, test methods, inspection rules, quality assurance period, marking, packaging, transportation and storage requirements of SZ series micro DC servo motors. This standard applies to SZ series micro DC servo motors (hereinafter referred to as motors). This series of motors are separately excited DC servo motors with commutators, which can be used as actuators in automatic control systems and can also be used as drive components. This series of motors are divided into two categories according to the operating environment conditions: ordinary type and humid tropical type (indoor). The humid tropical type motor has "TH" added after the ordinary type model. This series of motors is not suitable for environmental conditions with special requirements, such as: explosion-proof, oil-resistant, chemical corrosion-resistant, exposed to the sun, rain, etc. JB/T 1377.1-1999 SZ series micro DC servo motors JB/T1377.1-1999 Standard download decompression password: www.bzxz.net
