### Total power generated by a 3 phase motor. Please check my working?

Does this help you visualize it any better: - Maybe another hint: the voltage across each resistor is the RMS voltage you measured (assuming the generator output is balanced).

### How can I connect a 1-phase, 220-volt motor to a timer and relay switch to alternate between two power sources at set times?

First intuition: Why two relays? (Most) relays you can buy can switch between two leads, not just "off" and "on", and that's very desirable, because no matter how badly you mess up ...

### Solar cell failure

There are two tests to confirm the solar panel is working. Solar panels/cells are current sources. You need two specifications for the panel: ISC (current short circuit) and VOC (voltage open circuit)....

### 12 VDC to 380 VAC for 1 kW, 3-phase motor

Besides the 100 A draw from the battery mentioned already, the easiest way would be to get a 12 V DC -> 220-240 V AC (single phase) inverter and a VFD which accepts 230 V AC input and outputs 380 V ...

### Need motor to stop at 4 different points for steering

I'm thinking you can use a cam on the steering motor, fitted with a microswitch actuated by 4 detents, for each stop point. It would work like this: at rest: detent opens microswitch twist joystick: ...

### Need motor to stop at 4 different points for steering

My first thought is that you need some kind of information from the sprocket & chain mechanism, about its current position. One way of going about this is to have a fifth sprocket, which rotates ...

### Need motor to stop at 4 different points for steering

I think the question can be formulated as, I want to use a joystick to move a chair in one of four directions, F (forward), B (backward), L (left) or (Right). The chair has four motorised scooter ...

### Need motor to stop at 4 different points for steering

As all the wheels are linked to the chain as you state, then all you need is to drill holes or indents at the 4 relevant points on the sprocket matching the 4 points you need. A spring loaded ball ...

### Does the growler check also shorts to the armature metal body?

A growler is a tester that is basically like the primary of a transformer. If you bring a shorted armature coil near the growler, it will induce a current into the armature coil causing the "...

### Is thick or thin wire better for motor winding?

Having chosen the power of the motor, and its volume and weight, and the space available for winding, and so the weight of the copper, you have finished that part of the design. To first order, the ...

### How to tell if brushless DC motor is wired delta or Y?

You can take a look at connected cables of the copper coils. I'm going to use three-phase BLDC motor for example. From my understanding, Delta formation described as follows: End winding 1 connected ...

### Confusion understanding series/parallel relationship of mechanical components of a DC motor in Simulink Simscape

Your second picture may be a brushed DC motor with a fixed field provided by a coil instead of a permanent magnet. I wouldn't pay too much attention to this personally, it's not even in your simscape ...
