Octacom motor Germany Octacom model Octacom price

Octacom motor is a discrete value control motor that converts electrical pulse excitation signals into corresponding angular or linear displacement. This motor moves one step for each input electrical pulse, so it is also called a pulse motor. It is a micro special motor that converts electrical pulse signals into angular displacement to control rotor rotation. It serves as an actuator in automatic control devices. For each input pulse signal, the stepper motor advances one step, hence it is also known as a pulse motor. Stepper motors are widely used in peripheral equipment of digital computers, as well as in printers, plotters, and disk drives. The drive power supply of a stepper motor consists of a variable frequency pulse signal source, a pulse distributor, and a pulse amplifier, which provide pulse current to the motor windings. The operating performance of a stepper motor depends on the good coordination between the motor and the drive power supply. The advantages of stepper motors include no cumulative error, simple structure, easy use and maintenance, low manufacturing cost, and high ability to drive load inertia. They are suitable for small and medium-sized machine tools and applications with low speed and precision requirements. The disadvantages are lower efficiency, significant heat generation, and occasional "step loss".

Octacom motor performance

Although the working principle of the motor is similar to that of a split-phase single-phase asynchronous motor, the rotor resistance of the former is much larger than that of the latter. Therefore, compared with a single-unit asynchronous motor, a servo motor has three significant characteristics: 1, large starting torque. Due to the large rotor resistance, there is a clear difference compared to the torque characteristic curve of ordinary asynchronous motors. It allows the critical slip ratio S0 > 1, which not only makes the torque characteristic (mechanical characteristic) closer to linear but also provides a larger starting torque. Therefore, when the stator receives a control voltage, the rotor rotates immediately, featuring fast start-up and high sensitivity. 2, wide operating range. 3, no self-rotation phenomenon. For a normally operating servo motor, as soon as the control voltage is lost, the motor stops running immediately. When the servo motor loses control voltage, it operates in a single-phase state. Due to the large rotor resistance, the two torque characteristics produced by the interaction of the two rotating magnetic fields rotating in opposite directions in the stator with the rotor (T1－S1, T2－S2 curves) and the synthetic torque characteristic (T－S curve). The output power of AC servo motors is generally 0.1-100W. When the power frequency is 50Hz, voltages include 36V, 110V, 220, 380V; when the power frequency is 400Hz, voltages include 20V, 26V, 36V, 115V, and others. AC servo motors run smoothly with low noise. However, the control characteristic is nonlinear, and due to the large rotor resistance, losses are high and efficiency is low. Therefore, compared with DC servo motors of the same capacity, they are larger in volume and heavier in weight, making them suitable only for low-power control systems of 0.5-100W.

Octacom motor advantages

Motor advantages: Compared with asynchronous motors, permanent magnet synchronous motors have much higher efficiency values under light load. Their high-efficiency operating range is wide, with efficiency greater than 90% in the range of 25% to 120%. The rated efficiency of permanent magnet synchronous motors can meet the 1 level energy efficiency requirements of current national standards, which is their biggest advantage in energy saving compared to asynchronous motors. In actual operation, motors rarely run at full power when driving loads. The reasons are: on one hand, designers usually determine the motor power based on the extreme operating conditions of the load, but extreme conditions occur rarely. At the same time, to prevent motor burnout under abnormal conditions, designers further leave a power margin. On the other hand, motor manufacturers usually leave a certain power margin beyond the user's required power to ensure reliability. This results in most actually operating motors working below 70% of rated power, especially when driving fan or pump loads, where motors usually operate in the light load region. For asynchronous motors, light load efficiency is very low, while permanent magnet synchronous motors can still maintain high efficiency in the light load region.

Octacom motor performance

The motor is also known as a motor rotating at synchronous speed. The rotor is attracted and rotated by the surrounding rotating magnetic field generated by the applied AC current. It rotates synchronously with the speed difference between the rotating magnetic field generated by the AC current and the magnetic field generated by the armature current. Open-loop speed control is possible. Without other measures, it cannot start rotating at startup. The induction motor in a permanent magnet synchronous motor is more effective. If the frequency of the electric power applied at startup is high, the stopped rotor will not be able to follow and cannot rotate on its own. Therefore, if the drive power supply is not frequency-controlled, a separate starting motor can be provided, or other types of motors can be used. It has a built-in mechanism. Semiconductors have high controllability via inverters, used together with control circuits.
