Dimensions

Note

The following overall dimensions and dimension drawings are only applicable for self-ventilated 1LA7/1LA5 and 1LG6 motors with special insulation for voltages up to 690 V. For overall dimensions of 1LA8/1PQ8 motors with special insulation for voltages up to 690 V, see the section “Non-standard motors”.

For overall dimensions and dimension drawings for surface-cooled motors with standard insulation for voltages up to 500 V, see the relevant section.

Notes on the dimensions

Dimension designations according to DIN EN 50347 and IEC 60072.
Fits

The shaft extensions specified in the dimension tables (DIN 748) and centering spigot diameters (DIN EN 50347) are machined with the following fits:

Dimension designation	ISO fit DIN ISO 286-2
D, DA	up to 30	j6
	over 30 to 50	k6
	over 50	m6
N	up to 250	j6
	over 250	h6
F, FA		h9

K		H17
S	Flange (FF)	H17

The drilled holes of couplings and belt pulleys should have an ISO fit of at least H7.

Dimension tolerances

For the following dimensions, the permissible deviations are given below:

Dimension designation	Dimension	Permitted deviation
H	up to 250	–0.5
	over 250	–1.0
E, EA		–0.5

Keyways and feather keyways (dimensions GA, GC, F and FA) are made in compliance with DIN 6885 Part 1.

All dimensions are specified in mm.
