Three-phase asynchronous hub motor controller works
Master formula n1 = 60f / P, S = (n1-n) / n1, n = (1-S) 60f / P, at the same time understand their significance (very important), to be able to make flexible use of these formulas to calculate. Also remember: Usually bldc motor driver at rated load slip SN is about 0.01-0.06. Book to focus on the example grasp.

Three-phase asynchronous hub motor driver nameplate data
(1) Model: grasp the book’s examples.
(2) Rating: general knowledge, to master the rated frequency and rated speed, our frequency is 50 Hz.
(3) Connection method: a Y-shaped and angle.
(4) Insulation class and temperature rise: the definition of control allows the temperature rise.
(5) work: general understanding.
Three-phase asynchronous hub motor controller of the mechanical properties

Master the rated torque, maximum torque and starting torque relationship. The formula to master the book and be flexible calculated. Bearing in mind the following:
(1) in constant rotation, hub motor controller and the resistance torque of the torque must be balanced.
(2) When the load torque increases, the initial instant hub motor driver torque T (3) the general three-phase asynchronous hub motor driver overload factor is 1.8-2.2.
(4) hub motor controller had just started n = 0, s = 1.
