Jim selected an HW23-601 IP65 rated step motor because it was the most powerful motor that fit the customer’s budget and could survive the typical environment of a generator. A stepper motor is an electromechanical device it converts electrical power into mechanical power. Another issue is the motor back-EMF (generator) constant Ke, the ratio of output voltage to speed. F4D2 that is Fast Forward Feed Full Digital Drive. What are dual-motion hybrid actuators and where do they excel? Just cleaned up a 22kw generator from Harvey flood. The number of poles of a stepper motor determine the step size or number of subdivisions, or "full steps", if you like. The three phases are then activated using a DC source through the support of solid-state switches. Low Efficiency – Unlike DC motors, stepper motor current consumption is independent of load. If we use one coil, the resistance should be 2 ohms and the inductance is 1.7 mH. The motor moves one step when the direction of current flow in the field coil changes, reversing the magnetic field of the stator poles. Below is a full wave rectifier circuit. A typical 100-pole (1.8 degree) hybrid stepper motor will produce 25 times the AC frequency than a common 4-pole servo motor for the same RPM. FIGURE 1: Power flow for a synchronous generator. A typical stepper motor wind turbine generator will operate at around 200 RPM, so you need to ensure that the motor you choose will put out a high enough voltage for your needs when rotated at that speed. That means the peak efficiency is about 80%. As the polarity changes, each coil is given a push or a pull effect, thus moving the motor. By Ray LaChance, Development engineering manager Any electric motor will also output a voltage when it’s freely spinning.
