Answers of stepping motor and General Motors are the different, how to conduct electrical drying processes
"Student issues" stepper motors and General Motors differ?
The "solution" is a high running accuracy and control for stepper motor control of the characteristics of a good system components. In pulse mode, it works, each receiving one or several pulse, motor rotor one position, the distance can be very small.
Difference between stepper motors and General Motors Linear Actuator Motor is accept pulses for stepper motor control. Stepper motor * is such a ring distributor of electronic switching device through power excitation winding turns of order connected to a DC power supply. Due to the excitation winding is arranged in some sort of order in space, rotation and DC after the power is switched on, it forms a step change in rotating magnetic field in space, the rotation of the rotor stepping, as pulse frequency increases, the speed increases.
Now more commonly used stepper motors including reactive type stepping motors, permanent magnet stepper motors, hybrid stepper motors and single-phase stepping motor and so on. Reactive type stepping motor rotor route made of soft magnetic materials, poly-phase excitation windings on the stator, using magnetically induced changes in torque. At this stage, applications of reactive type stepping motor Gets the most.
"The students question" how to conduct electrical drying?
"The answer" electrical drying purposes is expelled winding tidal water in, improving insulation, insulation is very low, without drying, powered, easily cause insulation breakdown.
Motor dry, there are many ways to generally have two heat-drying and current heating methods. When dry, to control the temperature to avoid overheating, damage the electrical insulation, grade a insulation motor maximum drying temperature of 85 degrees, e-grade insulation should not exceed 95 degrees.
Thermal drying Non Captive Stepper Motor method is carried out in electric oven, oven vent at the top for easy draining moisture, most electric oven with automatic temperature control device, to maintain constant temperature. In addition there are other hot drying method, such as infrared.
Current heating method is to access current in the stator winding of electrical energy into thermal energy for drying, at the beginning of the current control in the motor rated current should be 20%-30%, and then gradually increased 50%--60%. generally available auto-transformer as power is easy to adjust can also be strung together in several volumes close to the motor, connected to the 220V AC.
Drying start, due to tidal heating evaporation,Stepper Linear Motor low insulation resistance, and then gradually increased, elevated resistance more and more slowly, finally on a certain numerical stability. Qualified above the value and stability when the insulation resistance up to 6 hours without constant, the process can be ended.
