Why can't you make an electric motor driver with two transistors?

Question

Electronics

Recently asked such a question, did not know what to answer and decided to ask here. I'm just starting to learn electronics.

Answer 1

it is not disclosed what is thought to be done through two transistors ??
they can be put in parallel to increase the switching current.
just need to get confused by balancing the current between them.
nominally low resistance resistor in the drain or emitter circuit.
it is also possible to make a half-bridge circuit for bipolar motor control from two transistors, but bipolar power is required.
if with a bipolar voltage, they make a bridge on 4 transistors and a unipolar supply.

Answer 2

Can. Just depending on which motor and which driver.

Answer 3

To control rotation in both directions, you need to be able to connect + -, then - to the motor + The transistor can switch the current flowing in
only one polarity - therefore, you need two transistors per motor pole, total 4.p
middle point, you can get by with two transistors, since one input of the motor can be attached to this very middle point, and the second can be connected through transistors (2pcs) either to + or to - relative to the midpoint.
This is not done because with battery power, you will need twice as many batteries, and with stationary power, a power source with 2 times more power, half of which will idle.
