Document Type and Number:
WIPO Patent Application WO/2020/135688
Kind Code:
A1
Abstract:
A separately excited direct-current motor driving device (100) and electric equipment. The separately excited direct-current motor driving device (100) comprises: a separately excited direct-current motor (10); a direct-current power supply; an armature chopper (20, 20a, 20b); and an excitation chopper (60), wherein the armature chopper (20) has m armature chopper units (21, 21a, 21b), each of which has a pair of armature power supply output terminals (221, 222, 223, 221a, 222a, 223a, 221b, 222b, 223b) and w armature switch control ends (2110, 2110a, 2120a, 21110b, 21120b, 21210b, 21220b), the excitation chopper (60) has n excitation chopper units (61), each of which has a pair of excitation power supply output terminals (621, 622, 623), and the separately excited direct-current motor (10) has m pairs of armature external wiring terminals (151, 152, 153) and n pairs of excitation external wiring terminals (161, 162, 163), the m pairs of armature external wiring terminals (151, 152, 153) being connected in one-to-one correspondence to the m armature power supply output terminals (221, 222, 223, 221a, 222a, 223a, 221b, 222b, 223b), the n pairs of excitation external wiring terminals (161, 162, 163) being connected in one-to-one correspondence to the n pairs of excitation power supply output terminals (621, 622, 623), m being a positive integer not less than 2, n being a positive integer not less than 2, and w being 1, 2, or 4.
