1、新的或长期停用的的电机，使用前应检查绕组间和绕组对地绝缘电阻，并应在电机冷却状态下测量。
Should be checked before new or long-term disabled motor Hangzhou lifting platform, using inter-winding and winding insulation resistance, and should be measured at the motor cooling state.

2、检查厂房升降平台的电机的外表有无裂纹，各紧固螺钉及零件是否齐全，电机的固定情况是否良好及电机传动机构的工作是否可靠。
Check the appearance of the motor plant in Hangzhou lifting platform for cracks, the fastening screws and parts are complete, fixed the motor is good and the motor drive mechanism work is reliable.

3、根据铭牌所示数据，如电压、功率、频率、联结、转速等与电源、负载比较是否相符，升降平台电机的通风情况及轴承润滑情况是否正常。
According to the data shown in the nameplate, such as voltage, power, frequency, link, speed and power, such as the load is relatively consistent, ventilation and bearing lubrication Hangzhou lifting platform motor is normal.

4、扳动厂房升降平台电机转轴，检查转子能否自由转动，举刷机构是否灵活，举刷手柄的位置是否正确及电机接地装置是否可靠。
Hangzhou plant lifting platform pulled the motor shaft and check the rotor can rotate freely, move the brush mechanism is flexible, move the brush handle is correctly positioned and electrical grounding device is reliable.
