HKS motor Germany HKS model HKS price

The HKS motor is a device that places the rotor in a rotating magnetic field, where it obtains a torque under the action of the rotating magnetic field, causing the rotor to rotate. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. It was invented by electrical engineer Nikola Tesla in 1887. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. The stator is the non-rotating part of the electric motor, and its main task is to generate a rotating magnetic field. The rotating magnetic field is not achieved by mechanical means. Instead, alternating current is passed through several pairs of electromagnets, causing their magnetic pole properties to change cyclically, thus equivalent to a rotating magnetic field. This type of motor does not have brushes or slip rings like DC motors. Depending on the type of AC power used, there are single-phase motors and three-phase motors. Single-phase motors are used in applications such as washing machines and electric fans; three-phase motors are used as power equipment in factories.

HKS motor service life

Motor life is related to various factors such as functional failures caused by insulation deterioration, wear of sliding parts, and bearing deterioration. In most cases, it depends on the condition of the bearings. Bearing life includes two types: mechanical life and lubricant life. Bearing life is defined as follows: 1, lubricant life due to thermal deterioration of the lubricant; 2, mechanical life caused by operational fatigue. In most cases, the effect of heat on lubricant life is more significant than the effect of the load weight on the bearing on mechanical life. Therefore, motor life is estimated based on lubricant life. The most significant factor affecting lubricant life is temperature, which greatly influences the service life.

HKS motor fault analysis

The influencing factors and inspection methods for difficult cold starts and difficult hot starts in motor faults are largely the same. Regarding the air-fuel mixture concentration, there are two situations: mixture too lean and mixture too rich. Faults affecting fuel supply may occur in fuel quality, fuel pump, fuel filter, fuel pressure regulator, cold start system, injectors, and water temperature sensors. Faults affecting air intake mostly manifest as clogged air filters, air intake system leaks, and idle speed control faults.

HKS motor performance

Although the working principle of the motor is similar to that of the split-phase single-phase asynchronous motor, the rotor resistance of the former is much larger than that of the latter. Therefore, compared with single-unit asynchronous motors, servo motors have three significant characteristics: 1, high 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 control voltage, the rotor rotates immediately, exhibiting fast starting 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 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 resultant 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 characteristics are nonlinear, and due to the large rotor resistance, losses are high and efficiency is low. Therefore, compared to DC servo motors of the same capacity, they are larger in volume and heavier in weight, making them suitable only for small-power control systems of 0.5-100W.
