(The electric motor has been used for retrofitting diesel-powered
trucks to electric or hydrogen-powered ones. A hydraulic pump can also
be added to it. A drawing of the electric motor with an attached pump
is provided.)
The Permanent Magnet Synchronous Motor (PMSM) is an AC electric motor
that uses permanent magnets in the rotor instead of electromagnetic
windings, resulting in high efficiency, power density, and a high
torque-to-inertia ratio. These motors require complex, digitally
controlled inverters for operation and are used in high-performance
applications such as robotics, electric vehicles, and high-efficiency
appliances like washing machines.
Rotor:
Unlike induction motors, the rotor is equipped with permanent magnets
(often neodymium), not wound coils, which eliminates rotor current and
associated losses.
Stator:
Similar to a conventional AC motor, the stator has windings that, when
supplied with alternating current, create a rotating magnetic
field.
Synchronous Speed:
The magnetic field of the rotor locks to the stator’s rotating
magnetic field, causing the rotor to turn at exactly the same speed
(synchronous speed).
Control:
PMSMs require a Variable Frequency Drive (VFD) or digital controller,
often implementing advanced algorithms such as Field-Oriented Control
(FOC), to properly energize the stator windings and manage speed and
torque.
Brushless Design:
The absence of brushes contributes to high reliability, low
maintenance, and quiet operation.
Advantages:
High S51264513 Efficiency:
Permanent magnets in the rotor eliminate energy losses in the rotor,
and their higher power density means they can operate more efficiently
than asynchronous (induction) motors.
High Power Density:
They provide a high power-to-volume and torque-to-inertia ratio,
allowing for more compact and lighter designs with greater torque.
Precise Control:
They deliver accurate and smooth speed and torque control across the
entire speed range, including at zero speed.
