GENERAL INFORMATION
LEESON MOTOR MODEL NUMBER
NOMENCLATURE
All LEESON motors, both stock and custom, have a catalog number
and a model number. The model number appears on the motor’s
nameplate and describes pertinent electrical and mechanical features
of the motor. An example follows along with a listing of the various
letters and positions used.
Odd frequencies other than 50 Hz show synchronous speed code.
DC and special motors may have one, two, or three digits indicating
motor speed rounded to the nearest hundred RPM.

SCR PM DC MOTORS ON PWM POWER SUPPLIES
Pulse width modulated DC controls have a voltage output similar to pure
direct current which has a form factor of 1.00. SCR thyristor drives, such as
the SPEEDMASTER® controls listed on page 83, have a form factor of 1.4.
LEESON stock SCR rated motors can also be used with PWM controls. In
fact, the motor’s HP rating can be increased because of less heating in the
motor. In addition, the motor will operate quieter and the brush life will be
extended.

MOTOR EFFICIENCY TEST METHODS
Performance data of single phase motors is determined by using I.E.E.E. Std.
114 (Method B), three phase motors by I.E.E.E. Std. 112 (Method B). Motor
efficiency is calculated using CSA C390. These testing methods meet the
requirements of EPACT of 1992 and most utility companies.
