Construction of d.c. PM commutator motors with laminated-core rotors:(a) slotted rotor, (b) slotless rotor.
The use of permanent magnets in construction of permanent magnet dc motors brings the following benefits:
The use of permanent magnets in construction of permanent magnet dc motors brings the following benefits:
• no electrical energy is absorbed by the field excitation system and thus there are no excitation losses which means substantial increase in efficiency,
• higher power density and/or torque density than when using electromagnetic excitation,
• better dynamic performance than motors with electromagnetic excitation(higher magnetic flux density in the air gap),
• simplification of construction and maintenance,
• reduction of prices for some types of machines.
