MOTORS
Space Heater (SH)
Motors subjected to extreme temperature fl uctua-
tions or severe climatic conditions can be damaged
by the formation of condensation. NORD can provide
motor anti-condensation space heaters inside the
motor to heat up the windings when the motor is
not operating. This will prevent moisture from con-
densing inside the motor. The space heaters must
not be switched on while the motor is running.
Class H Insulation (ISO H)
NORD motors can be manufactured with class H in-
sulation system. Standard NORD motors include
double coated magnetic wire windings. When these
windings are paired with a class H insulation it
provides extra temperature capacity for the motor
and will lengthen the motor’s life. Class H insulation
rated motors are also an advantage in some severe
applications:
• Increased ambient temperature installations –
above 40°C (104°F)
• Increased elevation installations –
above 3300 ft (1000 m)
• Applications with a high number of starts per hour.
• Meets class H insulation motor specifi cations
• Lower operating frequency when used with
frequency inverter systems
• For additional information on insulation class see
page
694.
High Resistance Rotor (WU)
Using Silumin rotor material, NORD offers a high re-
sistance rotor to soften the motors operation and
allow higher overload torques.
Single Phase Motors, 60Hz (ECR)
The ECR series of single phase motors is intended
for demanding operation at 60Hz with a supply
voltage of 115V or 230V. The permissible voltage
range is 115/230V +/- 10%. The ECR motors have a
1.15 service factor and are available from 0.16 - 2
hp.
