2.3 Cooling / Construction type (b)
8LS b c d . ee nnn ff gg - h see "Order key" on page 13
8LS three-phase synchronous motors are available in cooling types 8LSA, 8LSC, 8LSO and 8LSP. Cooling type
8LSE is only available upon request. All motors are based on cooling type A (elongated, slim) and can deviate in
this, the cable connection or mounting type.
The cooling types are distinguished by a character (c) in the model number.

1) Cooling type E is only available upon request for sizes 4, 6 and 8.
8LSA
Cooling type 8LSA is self-cooling and has a slim, elongated design.
These motors must be attached to the machine with the mounting flange, which also serves
as a cooling surface.
8LSC
Cooling type 8LSC is based on motors with cooling type 8LSA. These motors are externally
cooled and differ only by a fan module mounted in the area of the B-side bearing.
These motors must be attached to the machine with the mounting flange, which also serves
as a cooling surface.
Depending on the mounting situation, the attached fan module increases the nominal torque
(M
N
), nominal current (I
N
), stall torque (M
0
) and stall current (I
0
) by 30% compared to the
motors with cooling type 8LSA.
8LSO
Cooling type 8LSO is self-cooling and has a slim, elongated design.
These motors can be mounted to the machine with the mounting flange, which also serves
as a cooling surface, or with the mounting base. If the motor is only mounted with the mount-
ing base and not with the mounting flange, the continuous power is reduced in S1 operation.
8LSP
Cooling type 8LSP is based on motors with cooling type 8LSO. These motors are externally
cooled and differ only by a fan module mounted in the area of the B-side bearing.
These motors can be mounted to the machine with the mounting flange, which also serves
as a cooling surface, or with the mounting base. If the motor is only mounted with the mount-
ing base and not with the mounting flange, the continuous power is reduced in S1 operation.
Depending on the mounting situation, the attached fan module increases the nominal torque
(M
N
), nominal current (I
N
), stall torque (M
0
) and stall current (I
0
) by 30% compared to the
motors with cooling type 8LSO.
For transport reasons, this cooling type always has mounting base.
