Stop electric motor when toy elevator reaches end of travel

simulate this circuit – Schematic created using CircuitLab If SW1 is in the centre-off position the elevator does not move If SW1 is in the 'up' position (shown) the elevator goes up until limit ...

DC motor MOSFET driver (with flyback diode) keeps burning through

Yeah so there's a few things here. First up, your mosfet turns off WAY too slow for something you are trying to do high current with. Switching speed has to do directly with the gate resistor used to ...

How to build a homemade diy motor generator

No voltage? Even a single wire loop should catch something measurable if a magnet was moved nearby. Possible reasons: The movements of your magnet do not cause remarkable flux variations through the ...

Can one connect 2 or more DC motors of same or different excitations in series or parallel combination,and how does it work

Ideal DC permanent magnet (PMDC) motors run at a speed proportional to voltage, and with a torque proportional to current. For non-ideal motors, preface 'proportional' with 'approximately'. This means ...

Thermal efficiency circuit to move an DC electric actuator with PWM

Theoretically, with properly designed PWM, the power dissipation in the MOSFET should be very low, not requiring a large heat sink. There are three power states: Off: The MOSFET has very high ...

Thermal efficiency circuit to move an DC electric actuator with PWM

I would just use a logic-level N-channel MOSFET as shown. 1 kΩ for the gate resistor is a bit high, try dropping it to 200 Ω or so depending on your MCU's current handling capability, or use a ...

Can one connect 2 or more DC motors of same or different excitations in series or parallel combination,and how does it work

Parallel combinations will work as long as the power source can provide enough current. You need to be careful with this as there is a large surge current on startup and the power source needs to be ...

How can I determine the input voltage for running a DC motor?

I used google translate on the motor label image. The result is: I.e. from the label the voltage is 110 V DC.
