Abstract:
To solve the current problem of a single
magnetic coupler speed regulation method, a
permanent magnet (PM) rotatable magnetic coupler
structure is proposed, named magnet-rotating-type
axial magnetic coupler (MAMC). The MAMC can be
speed regulated in three ways: through air gap
regulation, rotary regulation, and composite
regulation. Then, a test platform of MAMC was built
to carry out experimental research on speed
regulation model of constant torque load, quadratic
rate load and constant power load. The results show
that the composite speed regulation method has a
wider speed range compared to the air gap speed
regulation method under the quadratic rate load speed
regulation model. Under the constant torque load and
constant power load speed regulation model, the
composite speed regulation method not only has a
wider speed range but also has a larger transfer torque
compared to the air gap speed regulation method.
