Energy efficiency is a main focus area related to CO2 emissions and industrial pollution. Across borders legislation and Minimum Energy Performance Standards (MEPS) are put into force to improve the efficiency of electric motors. The European MEPS are defined in the Ecodesign directive and Hoyer IE4 fulfils these future regulations.
From July 1 2023 all electric motors between 75-200 kW that are commissioned for land-based industrial applications within EU/EEA must be IE4 or higher. Hoyer Motors are ready to support in the pursuit of energy efficiency.
HMCX explosion proof marine motors are characterised by high material quality and a proven robust design. They are designed according to international standards in conformity with below.
The motors are low voltage three-phase TEFC motors, and designed in protection enclosure „db“. They can be used in zone 1 explosive atmospheres, group of use IIB/IIC covering all industries except mining. In these areas an explosive atmosphere can occur during normal operation (zone 1). Dangerous zones in the marine and oil & gas industries occurs on many vessel and platform types including gas carriers, semi-subs, tankers, FPSO’s, FSO’s, FLNG’s, FSRU’s etc.
HMCX motors are with cast iron housing, premium quality bearings and provided with ATEX and IECEx certified blind plugs. Motors frame size 80-250 are with closed bearings greased for life while frame size 280-400 comes with re-greasable open bearings. All motor sizes have tropical insulation and are equipped with winding heater and 3xPTC as. As standard motors have C3L coating according to ISO 12944-5:2018 in color RAL 9005 low gloss.
The range is designed to offer flexible product solutions according to customer and application demands. A variety of options are available including Exe protection, larger size motors, special bearings, higher IP class and various measuring systems.
