Roller with built-in motor, controller for roller with built-in motor, roller system with built-in motor, and geared motor

摘要

The present invention addresses the problem of developing a motorized roller and a controller for a motorized roller, the motorized roller requiring a smaller number of wires in comparison to the prior art. In the invention, a motorized roller has a cylindrical roller main body, and has a motor 12 and a decelerator built into the inside thereof. A voltage signal forming circuit 56 is constructed within the roller main body. The voltage signal forming circuit 56 is configured by magnetic pole-corresponding switching elements Q1, Q2, Q3 for switching ON and OFF according to output from magnetic pole detection means H1, H2, H3, a temperature-dependent switching element Q4 for switching ON and OFF according to output from an abnormal temperature detection means 57, and a plurality of resistors R1-R7. The voltage signal forming circuit generates voltage according to the detection condition of the magnetic pole detection means H1, H2, H3, and the detection condition of the abnormal temperature detection means 57.
