Title

Brush Type Generator

Brief Introduction

Check the external situations of Z2 brush type generator once box-opening completed, checking if there is drop, collision, exposure to the rain and other phenomenon. The supported accessories of motor are in well conditions (tachogenerator, optical-electricity encoder as well as fans, etc).

Mechanical check. Check if all fasteners are well fastened. Rotate the armature by hands to check if there is block, crash or friction. Open the commutator cover or blinds to check if there is pollution, steam, or rust on the surface of commutator and check if the brush is in completed condition.

Check the insulation resistance. The winding-to-casing insulation resistance should be less than 1 Megohm under indoors temperature. If there are no any problems in accordance with motor checking, please arrange adjustment and installation as per the above requirements and check if each accessory wiring is correct and wiring of grounding is good, safe and reliable.

As for motors with non-adjustable power supply, starter should be used during start-up period. Adjust the starter resistance value to maximum firstly and cut off gradually during start-up. As for external ventilation motor, start the ventilator and separate excitation motor firstly and then input the rated excitation voltage, gradually rise up the armature voltage to rated voltage. The start-up current should be controlled less than 2 times of rated current, the instant starting impulse current should no larger than 3 times of rated current.
