Problems solved by technology

However, the opening height of the rolling door cannot be precisely controlled; the operating speed of the rolling door can only be adjusted within a certain range according to the gear position
The heavy motor of the rolling shutter door needs a large output torque to roll it up, and the working current is large, which can easily cause the motor to become hot

Abstract

The invention relates to a motor driving device for a rolling shutter door, in particular to a brushless motor driving device for the rolling shutter door. The brushless motor driving device for the rolling shutter door comprises a driving circuit for driving a brushless motor to work and a feedback circuit for detecting working parameters of the brushless motor and feeds back the working parameters to the driving circuit; the driving circuit is electrically connected with the brushless motor, the feedback circuit is electrically connected with the brushless motor to collect the working parameters of the brushless motor, and the feedback circuit is electrically connected with the driving circuit to transmit the working parameters to the driving circuit.

Description

technical field [0001] The invention relates to a motor driving device for a rolling door, in particular to a brushless motor driving device for a rolling door. Background technique [0002] Many modern workshops and large warehouses require maintaining a good air environment, constant temperature and humidity, etc. As a rolling shutter door that blocks the circulation of indoor air and outdoor air, it should be able to open and close at high speed, and it should also have a variety of operation modes to meet the needs of different occasions and improve work efficiency. The existing rolling door machine is generally controlled by an AC motor plus a frequency converter. For example, the Chinese invention patent with the application publication number CN104267623. The idle parameters are used as the parameters of the controller. The controller communicates with the frequency converter through the RS485 communication circuit, reads the parameters of the frequency converter cyc...
