Match voltage, load and operating speed; avoid overload and prolonged stall.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003eOne selected motor with its power\/control leads. A bracket and BLDC speed controller are included only when named in the package. The controller package does not include a power supply or FG speed-measurement module.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eDoes the motor need an external three-phase driver?\u003c\/h3\u003e\u003cp\u003eIts Hall commutation drive is built in. Use the documented DC power and logic\/control inputs; the optional board provides a convenient speed-control interface.\u003c\/p\u003e\u003ch3\u003eDoes the optional board measure FG speed?\u003c\/h3\u003e\u003cp\u003eNo. Keep the green FG lead isolated from this board, or connect it only to a suitable separate measurement circuit.\u003c\/p\u003e\u003ch3\u003eCan the blue control
