Arrangement for synchronization of the rotation speeds of at least two electronically commutated DC motors

摘要

In the case of an arrangement for synchronization of the rotation speeds of at least two electronically commutated DC motors (EC motors), one of which is a master motor whose rotation speed can be regulated and the remainder of which are subordinate motors, in order to create simple measures for reliable and exact synchronization it is provided to use the signal information from rotor position identification and/or rotation speed signals from the master motor (1) as reference variables for the rotation speeds of the secondary motors (7, 8, 15).
