The T200 is a brushless motor that needs the ESC to function. An ESC has three small input wires, usually terminated in a small 3-pin black plug (servo plug).
Of those three small wires, the red and black wires are +5vdc and ground. The other wire, usually yellow or brown, is the signal wire. ESC’s can’t just be switched on and off, they need a PWM signal, like that provided by an RC receiver.
You can control the ESC with a servo tester, if you like. That would be the simplest way. Get one that has a slide switch to select the ‘mode’, otherwise when power is applied they revert to ‘auto’, which would rev, reverse, rev the motor constantly.
