Thermal time constant T
th
The thermal time constant denes the temperature rise of the motor winding when the motor
load is suddenly increased (step increase) up to the permissible S1 torque. The motor has
reached 63% of its S1 nal temperature after T

A.2 Environmental compatibility
Environmental compatibility
• Environmental aspects during development
When selecting supplier parts, environmental compatibility was an essential criteria.
Special emphasis was placed on reducing the envelope dimensions, weight and variety of
metal and plastic parts.
Eects that impair paint-wetting can be excluded (PWIS test)
• Environmental aspects during production
Supplier parts and the products are predominantly transported in re-usable packing.
Hazardous materials do not have to be transported.
The packing materials themselves essentially comprises paperboard that is in compliance
with the Packaging Directive 94/62/EC.
Energy consumption during production was optimized.
Production has low emission levels.
• Environmental aspects for disposal
Motors must be disposed of carefully taking into account domestic and local regulations in
the normal recycling process or by returning to the manufacturer.
The following must be taken into account when disposing of the motor:
Oil according to the regulations for disposing of old oil (e.g. gearbox oil when a gearbox is
mounted)
Not mixed with solvents, cold cleaning agents or remains of paint
Components that are to be recycled should be separated into:
– Electronics scrap (e.g.encoder electronics, sensor modules)
– Scrap iron
– Aluminum
– Non-ferrous metal (worm gears, motor windings)
