SIBONI motor Germany SIBONI model SIBONI price

SIBONI motors are AC motors that generate electromagnetic torque through the interaction between the rotating magnetic field in the air gap and the induced current in the rotor windings, thereby converting electrical energy into mechanical energy. Three-phase asynchronous motors are mainly used as motors to drive various production machinery, such as fans, pumps, compressors, machine tools, light industrial and mining machinery, threshers and crushers in agricultural production, and processing machinery for agricultural and sideline products, etc. They feature simple structure, ease of manufacturing, low cost, reliable operation, durability, high operating efficiency, and suitable working characteristics.

SIBONI motor performance

The output torque of the motor decreases as the speed increases, and drops sharply at higher speeds, so its maximum operating speed is generally between 300 and 600RPM. AC servo motors provide constant torque output, meaning they can output rated torque within their rated speed (generally 2000RPM or 3000RPM), and provide constant power output above the rated speed. Four, overload capabilities differ; stepper motors generally do not have overload capability. AC servo motors have strong overload capability. Five, operating performance differs; stepper motor control is open-loop control. If the starting frequency is too high or the load is too large, step loss or stalling may occur. If the speed is too high when stopping, overshoot may occur. Therefore, to ensure control accuracy, acceleration and deceleration must be handled properly. AC servo drive systems use closed-loop control. The driver can directly sample the feedback signal from the motor encoder, forming internal position and speed loops, generally avoiding the step loss or overshoot phenomena seen in stepper motors, resulting in more reliable control performance. Six, speed response performance differs. It takes 200 to 400 milliseconds for a stepper motor to accelerate from standstill to its operating speed (generally several hundred RPM). AC servo systems have better acceleration performance. Taking the Sanyo 400W AC servo motor as an example, it takes only a few milliseconds to accelerate from standstill to its rated speed 3000RPM, making it suitable for control applications requiring rapid start-stop operations. In summary, AC servo systems outperform stepper motors in many aspects. However, stepper motors are often used as actuator motors in applications with lower requirements. Therefore, in the design of control systems, factors such as control requirements and cost must be comprehensively considered to select the appropriate control motor.

SIBONI motor starting methods

Motor starting methods include direct starting and reduced-voltage starting. Reduced-voltage starting includes: autotransformer compensation starting, star-delta switching starting, and extended-delta starting. Generally, small and medium-sized squirrel-cage asynchronous motors can be started directly. Direct starting equipment is simple and the method is convenient. However, the starting current is large and the starting torque is small. Large-capacity squirrel-cage asynchronous motors generally start by reducing the voltage at the terminals of the stator windings. Reduced-voltage starting can reduce the starting current, but inevitably reduces the starting torque. Various reduced-voltage starting methods are introduced below: Autotransformer compensation starting: Starting voltage = voltage reduction factor × rated voltage; Starting current = voltage reduction factor × starting current (direct); Starting torque = square of voltage reduction factor × starting torque (direct). Characteristics of the starting method: The motor stator windings start via an autotransformer for voltage reduction, and the autotransformer is disconnected after starting. Advantages and disadvantages: 1 Small starting current, 2 Starting control equipment cannot be complex, 3 Equipment is relatively expensive, but the starting torque is larger than that of the star-delta conversion method, so it is widely used. Star-delta conversion starting: Starting voltage = 0.577 × rated voltage; Starting current = 1/3 × starting current (direct); Starting torque = 1/3 × starting torque (direct). Characteristics of the starting method: The motor stator windings are connected in star configuration during starting, and switched to delta configuration after starting. Advantages and disadvantages: 1 Small starting current, 2 Small starting torque, 3 Frequent starting is possible, 4 Low price, suitable for motors with delta-connected stator windings, generally used for light-load starting of small-capacity motors. Extended-delta starting: Starting voltage = 0.78 × rated voltage (depends on the stator winding tap voltage); Starting current = 0.6 × starting current (direct); Starting torque = 0.6 × starting torque (direct). Characteristics of the starting method: The motor stator windings are connected in an extended-delta configuration during starting, and switched to delta configuration after starting. Advantages and disadvantages: 1 Relatively small starting current, 2 Relatively large starting torque, 3 Frequent starting is possible, 4 Only applicable to motors with intermediate taps on the stator windings. Secondly, soft starters and variable frequency drives are widely used. They are convenient to control and can be promoted for small-capacity equipment. For large-capacity, high-voltage motors, they should be used with caution. Although this technology is mature, the presence of non-linear components in the circuit generates significant harmonic content that pollutes the power supply. Despite the availability of harmonic mitigation equipment, highly irregular waveforms still exist in low-voltage circuits, affecting the normal operation of office electronic equipment and potentially causing capacitor breakdown in the circuit.

SIBONI motor starting methods

First motor starting method: Split-phase starting, assisted by an auxiliary starting winding. Its starting torque is not large. The operating speed remains roughly constant. It is mainly applied to motors for electric fans, air conditioner fans, washing machines, etc. Second method: When the motor is stationary, the centrifugal switch is closed. Upon powering on, the starting capacitor participates in the starting process. When the rotor speed reaches 70% to 80% of the rated value, the centrifugal switch automatically opens, the starting capacitor completes its task and is disconnected. The starting winding does not participate in operation, and the motor continues to operate using the running winding coil. Third method: When the motor is stationary, the centrifugal switch is closed. Upon powering on, the starting capacitor participates in the starting process. When the rotor speed reaches 70% to 80% of the rated value, the centrifugal switch automatically opens, the starting capacitor completes its task and is disconnected. The running capacitor is connected in series with the starting winding to participate in operation. This connection is generally used in places with heavy and unstable loads, such as air compressors, cutting machines, and woodworking machine tools, as shown in Figure C. For motors with centrifugal switches, if the motor fails to start successfully within a short time, the winding coils will burn out quickly. Capacitance values: Dual-value capacitor motors have large starting capacitance and small running capacitance, with voltage resistance generally greater than 400 V. Forward and reverse control: Usually, the resistance of the starting winding and the running winding of this type of motor is the same, meaning the wire diameter and number of turns are identical. This type of motor is generally used in washing machines. This forward and reverse control method is simple and does not require complex changeover switches. For forward and reverse control, simply swap lines 1 to 2 or swap lines 3 to 4 to achieve reversal. Identification of starting and running windings: Usually, the DC resistance of the starting winding is much larger than that of the running winding, which can be measured with a multimeter. Generally, the DC resistance of the running winding is a few ohms, while the DC resistance of the starting winding is tens to hundreds of ohms.
