binks motor Germany binks model binks price

binks motors are machines used to convert mechanical energy and AC electrical energy into each other. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have a simple structure, are easy to manufacture, are relatively robust, and can be easily made into high-speed, high-voltage, high-current, and large-capacity motors because they do not have commutators (see commutation of DC motors). The power range of AC motors is very wide, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 80s of the 20th century, the largest steam turbine generator had reached 150 ten thousand kilowatts.

binks motor operating mode

Generator excitation method powered by a separate source: Generators using this excitation method have a dedicated DC generator, known as a DC exciter. The exciter is generally coaxial with the generator, and the generator's field winding obtains DC current from the exciter through slip rings mounted on the main shaft and fixed brushes. This excitation method has advantages such as independent excitation current, reliable operation, and reduced auxiliary power consumption. It was the main excitation method for generators in the past few decades and has mature operational experience. The disadvantage is that the excitation regulation speed is slow and maintenance workload is high, so it is rarely used in units above 10MW. Excitation method without an exciter: In this method, no dedicated exciter is set up; instead, the excitation power is obtained from the generator itself, rectified, and then supplied to the generator's field winding, known as self-excited static excitation. Self-excited static excitation can be divided into two types: self-shunt excitation and self-compound excitation. The self-shunt excitation method obtains excitation current through a rectifier transformer connected to the generator outlet, which is then rectified and supplied to the generator field. This method has advantages such as simple structure, fewer devices, cost savings, and less maintenance workload. The self-compound excitation method, in addition to having a rectifier transformer, also has a high-power current transformer connected in series in the generator stator circuit. The function of this transformer is to provide a larger excitation current to the generator during a short circuit to compensate for the insufficient output of the rectifier transformer. This excitation method has two excitation power sources: a voltage source obtained through the rectifier transformer and a current source obtained through the series transformer. Excitation method powered by an AC exciter: Some modern large-capacity generators use an AC exciter to provide excitation current. The AC exciter is also mounted on the generator's main shaft. Its output AC current is rectified and supplied to the generator rotor for excitation. At this time, the generator's excitation method belongs to separately excited excitation. Since a static rectification device is used, it is also called separately excited static excitation. An AC pilot exciter provides the excitation current. The AC pilot exciter can be a permanent magnet measuring device or an AC generator with a self-excited constant voltage device. To improve the excitation regulation speed, the AC exciter usually uses a medium-frequency generator of 100——200HZ, while the AC pilot exciter uses a medium-frequency generator of 400——500HZ. The DC field winding and three-phase AC winding of this generator are both wound in the stator slots. The rotor has only teeth and slots without windings, resembling a gear. Therefore, it has no rotating contact parts such as brushes and slip rings, offering advantages such as reliable operation, simple structure, and convenient manufacturing process. The disadvantages are higher noise and larger harmonic components of the AC electromotive force.

Structurally, the motor rotor is equipped with permanent magnets to provide the operating point for soft magnetic materials, while the stator excitation only needs to provide a changing magnetic field without consuming energy for the magnetic material's operating point. Therefore, this motor has high efficiency, low current, and low heat generation. Due to the presence of permanent magnets, the motor has strong back electromotive force and good inherent damping, making it run smoothly with low noise and low-frequency vibration. To some extent, an inductor motor can be regarded as a low-speed synchronous motor. A four-phase motor can operate as a four-phase or two-phase motor (bipolar voltage drive must be used), whereas a reactive motor cannot. For example, four-phase, eight-phase operation (A-AB-B-BC-C-CD-D-DA-A) can fully adopt the two-phase eight-step operation mode. It is not difficult to find that the conditions are C=, D=. The internal winding of a two-phase motor is completely consistent with that of a four-phase motor. Low-power motors are generally directly connected as two-phase. For higher-power motors, to facilitate use and flexibly change the dynamic characteristics of the motor, the external wiring is often arranged as eight leads (four-phase). In this way, it can be used as a four-phase motor, or the two-phase motor windings can be used in series or parallel.

The motor allows stepless speed regulation. By controlling the opening degree of the intake or exhaust valve, i.e., controlling the flow of compressed air, the output power and speed of the motor can be adjusted to achieve the purpose of regulating speed and power. 2. It can rotate both forward and reverse. Most air motors can simply use a control valve to change the intake and exhaust direction, thereby achieving forward and reverse rotation of the output shaft, with instantaneous reversal possible. During forward and reverse conversion, the impact is minimal. A major advantage of air motor reversal is its ability to accelerate to full speed almost instantaneously. Vane air motors can reach full speed within one and a half revolutions; piston air motors can reach full speed in less than one second. Using a control valve to change the intake direction achieves forward and reverse rotation. The time for forward and reverse rotation is short, the speed is fast, the impact is small, and no load unloading is required. 3. Safe operation, unaffected by vibration, high temperature, electromagnetic fields, radiation, etc. Suitable for harsh working environments, it can operate normally under unfavorable conditions such as flammable, explosive, high temperature, vibration, humidity, and dust. 4. Has overload protection and will not fail due to overload. During overload, the motor only reduces speed or stops. When the overload is removed, it can immediately resume normal operation without causing damage to components. It can operate continuously at full load for a long time with low temperature rise. 5. Has high starting torque and can start directly with load. Starting and stopping are rapid. It can start under load. Starting and stopping are rapid. 6. Wide power and speed ranges. Power ranges from a few hundred watts to tens of thousands of watts; speed can range from zero to ten thousand revolutions per minute. 7. Easy to operate and maintain. Air motors have a simple structure, small size, light weight, high power, easy operation, and convenient maintenance. 8. Uses air as the medium, with no supply difficulties. Used air does not need treatment and releases no pollution into the atmosphere. Compressed air can be supplied centrally and transported over long distances. Due to these many advantages, air motors can work in harsh environments such as humidity, high temperature, and high dust. In addition to being used as power sources for rock drilling, drilling, mining, and loading equipment in mining machinery, they are also widely adopted in industries such as shipbuilding, metallurgy, chemical engineering, and papermaking.
