It is incorrect to compare plettenberg with XL motors and lehner 19 series and up...

Plettenberg motor can be compared with L-series motors. Being 4-pole motor makes it very torque motor but with limited RPM range. That is why not every ESC will handle it with ease. For example BK controllers do not have protection over high RPM (you can destroy batteries or ESC), while schulze controllers do have that (by limiting RPM). When 4-pole motor used you need to reduce RPM supported by ESC by factor of 2 (compared to 2-pole motor) and then do the comparison.

BK and Scultze can run up to 65000 with 2-pole motors
MGM Compro can do 150000 with 2-pole motors

With 4-pole that would be half and half.

Also plettenberg motor has poles in configuration which creates high magnetic friction (while it can be configured to self-cancelling), which can be useful in some applications and bad in others.

P.S. Somewhere I was reading that lehner motor are 4-pole motors is that correct? Haven't had one yet...
