Three main issues in gear motors that are currently on the market
1) The failure rate of the limit switch is too high, While the limit switch is locked when the gear motor is in operation, if the limit control switch fails, it causes serious damage to the window or curtain system.

2) The braking distance is too long, causing insufficient closure of windows and inadequate curtain covering, and this damages the whole system.

3) Motor burnout due to phase loss or overload of the power supply, greenhouse gear motors are mostly used in rural areas, so the power system often has phase loss, and if a technician fails to install the phase loss protection device in time, the motor will burn out.
