<p>An electric potential follower type limiting structure for a rolling-door motor, comprising a baseplate (10) fixedly installed on a frame (5); a fourth gear (13) is installed on a shaft (12); the shaft (12) passes through the baseplate (10) such that a safety clutch (8) is installed on the shaft (12); a potentiometer (11) passes through the baseplate (10) such that a first gear (6) and a second gear (7) are installed on the shaft (12) of the potentiometer; the second gear (7) is installed at a corresponding position of the baseplate (10); a third gear (9) is installed on the safety clutch (8); a motor gear (2) is installed on a motor clutch (3); the motor clutch (3) is installed on a motor (4); the motor (4) and a transmission chuck are installed on the frame (5); the motor (4) rotates to drive all parts to operate. Compared with existing encoder type electronic limiting, electronic limiting employed on a rolling-door motor is more precise, more reliable, and simpler, and is suitable for complicated working environments.</p> |
