The supply phases are connected to the three corners of the triangle.
How to Wire a High & Low Voltage Three-Phase Motor | Sciencing
This means that each supply phase is connected to two windings. Each winding has around V across it in UK that's V times sq root 3.
For US,it would be about V for a nominal V supply.
There is no neutral point or connection. The delta arrangement gives more power but usually require a motor to be started in star first. Rotation speed is usually a bit lower than the theoretical maximum rpm for 50Hz supply, rpm for 60Hz because there are some you.
See motor rating plate. Speed controllers are expensive because they have mcfaddens hook up party create variable supply frequency at high currents. That involves high power triacs or similar and lots of control circuitry. However, they work well and can usually be configured to give "soft start", which is desirable in some applications.

How to connect a three-phase motor - Electrical Engineering Stack Exchange
We mentioned a catch, earlier. That drawing we said to follow could be wrong. Before you connect any wires, check the drawing carefully. Before you actually make any bolted connections, verify the correct rotation using a rotation tester. Note that this must be the power supply ground conductor, not a mofor leading to a ground rod nearby.
