Samarium Cobalt (SmCo) magnets, of the Rare Earth class, have been available since the early 1970’s.
These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion. These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and environments.
SmCo magnets are manufactured by sintering or compression bonding. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30 to 45KOe are required to saturate SmCo magnets. AC Motor SmCo Tile Permanent Magnet
There are four main brushed motor types, including:
Series Motors. The stator is in series or identical with the rotor, causing their field currents to be identical. Characteristics: used in cranes and winches, great low speed torque, limited high speed torque.
Shunt Motors. The field coil is parallel (shunt) with the rotor, making the motor current equal to the sum of the two currents. Characteristics: used in industrial and automotive applications, excellent speed control, high/consistent torque at low speeds.
Cumulative Compound Motors. This type combines aspects of both series and shut types, making the motor current equal to the sum of both the series field and shunt field currents. Characteristics: used in industrial and automotive applications, has combined benefits of both series and shunt motors.
PMDC Motors (Permanent Magnet). The most common type of brushed electric motor, PMDC motors use permanent magnets to produce the stator field. Characteristics: used in commercial production of toys and appliances, cheaper to manufacture, good low end torque, limited high end torque.
Brushless Motors in the brushless category do not have a commutator and brushes. Instead, the rotor is a permanent magnet and the coils are on the stator. Rather than controlling the magnetic fields on the rotor, brushless motors control the magnetic fields from the stator by adjusting magnitude and direction of the current in the coils. One of the main advantages of brushless motors is its efficiency, which allows for greater control and production of torque in a more compact assembly.
