The most common fault of a vibrating motor is that the vibrating motor is overheated during operation. If the fault cannot be eliminated in time, the vibrating motor will burn out! In particular, vibration motors that have been used for more than half a year and more than one year, or vibration motors that have been opened and repaired by users themselves are more prone to overheating of the vibration motor! Below we will introduce effective measures to prevent overheating of the vibration motor!
The first is to understand the conditions of use of the vibration motor to ensure the normal use of the vibration motor.
1 vibration acceleration does not exceed 7g (g is the acceleration of gravity);
2 the ambient temperature does not exceed 40 ° C;
3 altitude does not exceed 1000m;
4 power frequency: 50HZ; 60HZ;
5 voltage 380V, 380-660V;
6 temperature rise is less than 80K (resistance method).
Secondly, the cause and treatment of the vibration motor overheating:
1. Reasons: 2. Processing method:
1 voltage is too high, so that the core is overheated; 1 immediately reduce the voltage or adjust the power transformer tap;
2 The vibration motor is overloaded or under voltage 2 Increase the voltage or replace the thicker wire;
Leading to excessive current and heating of the windings;
3 When the winding is removed, the thermal disassembly is improper, 3 repair the iron core to eliminate the fault;
Burn iron core;
4 The stator and the iron core are too close to each other and rubbed; 4 eliminate the rubbing point;
5 vibration motor overload or frequent start; 5 load shedding, control start according to the specified number of times;
6 cage rotor broken bars; 6 check and eliminate winding faults;
7 vibration motor phase loss; 7 resume three operations;
8 winding immersion paint is not sufficient when reloading; 8 using secondary dipping paint and vacuum dipping process;
9 The ambient temperature is too high, the air duct is blocked by dust; 9 Clean the motor, improve the ambient temperature, and adopt the cooling measures;

Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.
Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.
