On certain motors, like fractional HP induction motors (capacitor start, split phase, repulsion start), there is a starting coil and a running coil. If you try to reverse the motor at full speed, it won't. It has to slow down until the centrifugal switch engages, and preferably until it stops before you reverse it.ramonegumpert said:

Is it possible to form a h-bridge using 2 spdt relays?
What i can find on the net are h-bridges using 4 spst relays or using other types of relays.

Relays are used in h-bridges to control the direction of current flow in a motor or other high-power device. They act as switches, allowing current to flow in one direction or the other, depending on the state of the h-bridge.
The minimum number of relays required for an h-bridge is two. However, some h-bridges may use more than two relays for added functionality or to handle higher power loads.
Yes, it is possible to use transistors in place of relays in an h-bridge. However, transistors may not be able to handle as much current as relays, so they may not be suitable for high-power applications.
The number of relays used in an h-bridge can affect its performance in several ways. Using more relays can provide more precise control over the direction and speed of a motor, but it can also increase the complexity and cost of the h-bridge.
Using the minimum number of relays in an h-bridge can limit the functionality and precision of the device. It may also make the h-bridge more susceptible to malfunction or damage if one of the relays fails. Using more relays can provide a backup in case of a relay failure and can also allow for more advanced control of the device.
