Abstract : This paper introduces the working principle, structure, main technical parameters, and application of a linear motor-driven tippler. Compared with traditional electric tipplers, it has advantages such as simple structure, convenient maintenance, low failure rate, low cost, large starting torque, strong overload capacity, convenient control, and energy saving, making it an ideal new type of tippler equipment. Keywords : linear motor; tippler; primary and secondary rollers; magnetic field 1 Overview Tipplers are one of the important pieces of equipment in coal production processes. However, most existing tippler structures use AC rotary motors, which drive the rollers to rotate through a reduction system via friction wheels to achieve unloading. These tipplers are not only large in size and complex in structure, but also prone to failure, high maintenance volume, and high equipment cost. Furthermore, insufficient friction can lead to slippage and difficulty in tipping. To solve these problems, a new type of tippler with a linear motor is developed, which uses an arc-shaped linear motor for direct starting, acting as the secondary roller for tipping to achieve unloading. This linear motor tipper is not only simple in structure, easy to maintain, and has a low failure rate, but its rollers also obtain rotational torque through a spatial magnetic field, independent of friction and force. It has a large starting torque and strong overload capacity, making it a new type of tipper equipment. 2. Basic Working Principle As shown in Figure 1, imagine unfolding a rotary motor radially from a certain point, forming a stator in the shape of an arc. The stator (primary side) and rotor (secondary side) are then straightened, resulting in the linear motor shown in Figure 1. The basic working principle of the arc-shaped linear motor is the same as that of the rotary motor; the unfolded stator is called the primary, and the unfolded rotor is called the secondary. The primary of the linear motor tipper is the arc-shaped linear motor, and the secondary is the roller. When the primary winding is connected to a three-phase symmetrical AC power supply, an air gap magnetic field is generated. The distribution of this air gap magnetic field is similar to that of the rotary motor's magnetic field; it can be seen that the unfolded arc direction is sinusoidally distributed. When the three-phase power supply changes over time, the air gap magnetic field will move along an arc according to the phase sequence, hence it is called a moving magnetic field. Clearly, the moving speed of the moving magnetic field is the same as the linear velocity of the rotating magnetic field on the surface of the primary inner air gap, i.e., [b][align=center]For more details, please click: Research and Development of Linear Motor Tipplers[/align][/b]
