I have specs on the E-542. EC's model numbers seem to all be
even, so I think the odd numbers may indicate some customization
of the stock motor. Anyway, the E-542 is a basic PM motor,
5" long, 2.88" across the brush caps. There are 4 winding
options, dash 01 through 04.

Dash Kt Ke R Ohms L mH Imax

01 15.30 11.33 2.26 4.87 20

02 19.38 14.34 3.64 7.82 16

03 24.46 18.13 5.82 12.42 12

04 30.60 22.65 9.04 19.48 10


Kt is Oz-In/Amp; Ke is volts/KRPM

Max Cont. torque, 42.5 Oz-In; thermal R is 4.18 deg C/Watt

Elect time const = 2.15 mS
Mech time const= 8.5 mS

I hope this helps.
