Problems solved by technology

However, this structure still uses the motor to directly drive the door curtain, which has a greater impact on the door curtain
However, the commonly used planetary gear structure reduction device has a large volume, and the bearing capacity for starting with a large torque is relatively low.
However, fast doors using pure motor switches require a large number of mechanisms to ensure power supply.

Abstract

A motor for a high-speed door comprises a machine shell, an electric motor body arranged in the machine shell, a speed reducer connected with a rotary shaft and an output shaft of the electric motor body, and a hand-operating device connected with the rotary shaft of the electric motor body. The overload capacity of the motor is high, the motor is resistant to impact and the inertia moment is small.

Description

technical field [0001] The invention relates to a fast door motor and belongs to the field of motor manufacturing. Background technique [0002] Common high-speed doors currently on the market are generally driven by a motor, and the drive shaft of the motor drives the reel to rotate so that the door curtain of the high-speed door is rolled to achieve the purpose of opening and closing the door. Traditional high-speed doors often directly use high-speed motors to drive the door curtain, and the control is often fuzzy, resulting in loud noise in the lifting and lowering of the door curtain, strong collision, and short service life. [0003] Patent No. CN203499540 discloses a fast door motor installation structure, which installs the fast door motor parallel to the reel, and then drives the reel to work through sprocket transmission, which maximizes the area of ​​the fast door and improves safety. protective effect. However, this structure still uses a motor to directly driv...
