The M Permanent Magnet Motors series by Pacific Scientific is a family of permanent-magnet DC motors built around rugged mechanical construction and dependable industrial operation.
The series uses a permanent-magnet field with a wound armature, commutator, and brushes, giving it the basic architecture associated with brush DC motor control and strong starting torque. In Pacific Scientific’s PMDC construction, the motors use ceramic magnets, a steel frame, aluminum end bells, and ball-bearing-supported shafts for mechanical support and durability. The family is also positioned with multiple application-oriented options, including washdown, explosionproof, and co-engineered variants for specialized installations. From a performance standpoint, the series is characterized by good operating efficiency, lower field-related losses than wound-field DC designs, and suitability for controlled braking and reversing practices when applied within the limits described by Pacific Scientific.
