Motor:
1. AC induction motor can use vector control and VVVF control. If VVVF control adopted, speed sensor would be
not necessary. The method of control is simple, meanwhile, same controller can drive several similar motors.
2. Vector control, AC induction motor only needs speed information, angle information are not necessary. Therefore,
encoder only adopts increment. Besides, AC induction motor operates without initial position, during application
of door system, not necessary to study pole position and absolute encoder.
3. AC induction motor has no demagnetization problem. AC motor stall torque is rather big, can be applied to more door types.
Controller:
1. The method of control is simple, same controller can drive several similar motors.
2. It is applicable to door open width with heavy load.
Opening Range:
1. Opening width: 600-1400mm, 2 panels center opening or side opening
800-1400mm, 3 panels side opening
700-1800mm, 4 panels center opening
2000-3000mm, 6 panels center opening
2. Opening height: 2000mm or 2100mm
Door Panel Finish:
1. Door panel finish: painted, stainless steel(hairline, mirror, etching)
