Industrial AC: match the shaft and load before the efficiency label
The group's own catalogue names YE2/YE3 three-phase induction, YEJ electromagnetic-brake, YTPS/YVP variable-frequency and several high-voltage families. A conveyor or pump replacement needs the correct mechanical fit and starting method; a brake motor additionally needs a defined stopping load and brake supply. The broad AC range on MotorSourcing is a catalogue reference, not one rated motor.
Confirm before ordering Send load torque-speed curve, line voltage/frequency, starting topology or VFD, duty, frame/mounting, shaft/coupling, cooling, ambient and brake holding/stopping requirements. Ask for one ordering code, current performance sheet, outline drawing and brake wiring if applicable.

Control DC: decide motor, gearbox and electronics together
The company separates permanent-magnet brushed, brushless, servo and geared DC categories. The relevant question is often output-shaft speed and torque after a reducer, as well as feedback and controller behaviour, rather than motor no-load rpm. Its older corporate detail pages for a permanent-magnet and a brushless motor give category names and photographs but no complete ordering matrix.
Confirm before ordering Provide continuous and peak output torque, motion profile, gearbox ratio and backlash limit, supply and peak current, controller/encoder interface, envelope, duty and expected life. Require a quoted motor-plus-reducer configuration, torque-speed/current curves and connector/shaft drawings.

Vehicle ABS or vacuum pump: validate at the subsystem boundary
Shanbo's vehicle catalogue publishes individual ZDY motor test points for ABS and electronic-vacuum-pump duties. For example, the ZDY1618 vacuum-pump entry distinguishes 13 V no-load speed from a 0.2 N·m loaded point; ZDY1621 uses a different 12 V/0.1 N·m loaded point. These are separate variants and test conditions, not a composite performance promise. Motor performance alone does not approve the braking or vacuum system.
Confirm before ordering State pump or ABS module revision, electrical transient profile, duty and thermal envelope, functional and endurance requirements, interface drawing and system validation plan. Request the exact ZDY variant, current production revision, point-by-point test report and customer qualification scope.
