I. Motor parameters of household electric curtains
The technical parameters of electric curtain motors are divided into direct current (DC) motor and alternating current (AC) motor on the specific power supply, and AC is divided into Single-phase 220V and three-phase 380V, which are common, generally cannot be adjusted in speed. The on-off of the power supply determines the start and stop of the motor, and there is a reversing switch; more particular, there will be a speed control system and a stepper motor. There are also servo motors.
1. Electric curtain motors usually use 12 motors (small transformers are required).
2. The power varies from 6 to 24W, depending on the weight of the curtains you drive and other factors.
3. Usually, the speed of the motor is 100–200 rpm, it is too high and there is noise.
Second, How to wire the electric curtain motor
Currently commonly used electric curtain motors include strong current control motors and weak current (dry) Contact signal) two kinds; general roller blinds, Roman blinds use strong electric control, opening and closing blinds generally use dry contact signal control. According to the control method, there are generally three types of control methods: switch, remote control, and central control.
The remote control wiring is the easiest, just put a set of power supply or a socket in the curtain box.
For switch or central control, place a set of power supplies in the electric curtain box, and then route two sets of 3*1RVV lines (strong current) or a network cable (weak current) from the curtain box to the switch In the bottom box or in the central control box.
The general wiring method is to leave a set of power supply in the electric curtain box, and then distribute two sets of 3*1RVV lines to the switch or central control, so that no matter how it is controlled, it can be controlled.
Three, How to install electric curtains?
The first step: draw the line positioning, measure the track size
1. The accuracy of the line drawing positioning is to install the curtain track The key is to first measure the fixed hole distance and the size of the required installation track.
2. The accuracy of the line drawing and positioning is the key to installing the curtain track. First, measure the fixed hole distance and the size of the required installation track.
3. The total length of the track is the main transmission box (motor), the length of the track, and the auxiliary transmission box.
4. Arc track can be curved curtain track according to the radian of the building (Note: the radian shall not be less than 120°).
About the measurement method of curved curtain track:
1. Make the arc track as shown in the picture, and indicate the length of “A”, “B”, “C” and the angle of the arc track, and indicate the position of the main transmission box, single or double opening (Note: “A”, “” B” length includes the length of the main transmission case and the auxiliary transmission case).
2. For the arc-shaped path of the viewing platform, draw it according to the picture, and indicate (chord length), (arc height), (arc length). And indicate the location of the main gearbox. Whether it is single or double, the size refers to the inner or outer dimensions of the track. (Note: the arc length includes the length of the main transmission box and the auxiliary transmission box).
Step 2: Install the hoisting clips
Rotate the clips 90° to connect with the track, and use self-tapping screws to install the hoisting clips to the top plate (if Concrete structure, need to add expansion screw.
The third step: motor wiring
The fourth step: motor and track connection
The two ends of the crawler curtain track specially used for the motor are equipped with transmission boxes, the main transmission box connected to the motor, and the auxiliary transmission box at the other end. The specific operations are as follows:
1. Put the electric motor 90° into the main transmission box; (Note: the flat rotating shaft of the main transmission box should be consistent with the motor interface);
2. Rotate the motor 90 degrees clockwise;
p>
3. After the rotation is in place, push the insert into the transmission box to the limit position, it will be automatically locked, and the motor will be connected with the transmission box; so as not to damage the motor).
Step 5: Motor stroke adjustment
There is a set of gears and micro-switches at the end of the motor, and the motor wiring requirements are met Forward and reverse rotation, so as to realize the self-positioning of electric curtain opening and closing stroke.
