General specification for brushless DC torque motors
1 Scope
This document specifies the classification and model, technical requirements, inspection rules, inspection methods, inspection rules and delivery preparation of brushless DC torque motors.
This document is applicable to brushless DC torque motors (including assembled and split motors) of rotating mechanisms such as automatic driving steering wheel, machine tool turntable and robot base. It can serve as a reference for brushless DC torque motors in other equipment.
This document shall be used together with the Specific specification for brushless DC torque motors (hereinafter referred to as the Specific Specifications for Products). The technical indexes and additional special requirements of all kinds of brushless DC torque motors are stipulated in the Specific Specifications for Products.
This document does not contain requirements for motor drivers and sensors.
