These powerful pancake motors offer numerous additional advantages compared with conventional permanent magnet DC motors:
Flat design
Long life when operating with highest nominal values
High performance-to-weight ratio
Very smooth operation at low speeds
Good acceleration from idle state when fully loaded
Low inductance
Minimal brush sparking
Minimal radio interference
Various magnet materials: M type with ferrite magnets; N type with "rare earth magnets"
The N type delivers up to 2.5 times the performance and 3 times the torque of an M-type motor of the same size
