AI Thread Summary
To move a satellite receiver to any geostationary satellite, a unipolar stepper motor is preferred, with options for half-stepping or microstepping to enhance accuracy at low speeds. The motor will be mounted horizontally, utilizing a worm gear or similar mechanism for full 360-degree rotation. The user seeks recommendations for a motor rated to support a load of 5-8 kg. Additionally, there is a query about the applicability of telescope methods for this setup. The discussion emphasizes the need for precise motor selection to ensure effective satellite tracking.

Hey everyone: I have the following problem: as the title suggests I need to be able to move my satellite receiver to any geostationary satellite orbiting. I want to use a unipolar stepper motor and either half step, or I might Microstep the motor to get more accuracy. I am looking to operate it at very low speeds.

The motor will be oriented horizontally, and a worm gear or any other type of gear will be used to get the 360' motion. What I would like to know what rated motor should I get that can handle the satellite load of about 5-8kg?

The attached file is a basic diagram of the orientation of the motor.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
