General The Innomotics HV C series of motors shown in this catalog covers shaft heights up to 560 mm and a power range extending up to 2.5 MW (6 kV, 50 Hz, 4-pole). This motor series covers the entire high voltage motor market and all applications in safe area and explosion protected zones (Zone 1, 2, 21, 22). • Air-cooled: IP55, cooling IC411/IC416 (safe area, Ex ec, flameproof) • Water-jacket-cooled: IP55, cooling IC71W (safe area, Ex ec on request) The Innomotics HV C series has been developed for line (direct-on-line, DOL) and converter (variable-speed drive, VSD) operation. This means...

Online updates – Innomotics Portal You will continue to find current information about the Innomotics HV C motors in the Innomotics Portal: portal.innomotics.com Configurator Use the Siemens Product Configurator tool to get a motor drawing and/or a 3D STEP model (find link below). The quickest way to get a drawing there: Use the direct article number entry on the home page. Note Please note, that it is not possible to display all special accessories in standard dimension drawings and tables. Therefore no special terminal boxes, sensors, sleeve bearing monitoring and oil supply equipment...

1 Introduction 1.3 General information about converter operation General information about converter operation Speed-adjustable operation of motors in combination with converters can result in increased electric stress of the motor winding. The motor's self-cooling capabilities might be no longer enough to dissipate the heat losses, depending on the load profile and speed range of the converter operation. Due to the nature of explosion-protected motors and their demand for a defined maximum surface temperature, converter-related thermic effects must be considered. In the end, some of the...

2 General design 2.1 Mounting arrangements General design Mounting arrangements Types of construction The motors are supplied as standard in the following construction types: • IM B3 (IM 1001) • IM V1 (IM 3011) Construction types are designated according to IEC 60034-7 Code I (Code II). IM B3 (IM 1001) Standard mounting arrangements Other types of construction are available on request. Canopy for motors, type construction IM V1 A protective cover (canopy) is required if air-cooled motors in IP55 degree of protection are installed outdoors or in hazardous areas. A protective cover can be...

2 General design 2.2 Mechanical degrees of protection Mechanical degrees of protection The motors in the anti-friction and sleeve bearing design are available in IP55 degree of protection as standard, marked according to IEC 60034-5. Higher degrees of protection are available on request. Cooling methods Table 2-1 Innomotics HV cooling methods, marked according to IEC 60034-6 Cooling method Motor type Self-ventilated water-jacket-cooled motors Self-ventilated rib-cooled motors Forced ventilated rib-cooled motors © Innomotics 2024 Innomotics HV C Catalog D 84.2

3 Main terminal boxes 3.1 General Main terminal boxes Terminal box standard placement for IC411/IC416 and IC71W Main terminal boxes are mounted on top of the motor by default, cables from the right side (see picture below), optional from the left-hand side. The terminal boxes can be rotated in 90° increments. Alternatively, it’s possible to switch the main terminal box to the left or to the right side. A neutral point terminal box can be mounted on request. The standard position of the neutral point terminal box is opposite the main terminal box. Standard terminal box mounting, water-cooled...

3 Main terminal boxes 3.1 General Standard terminal box mounting, air-cooled motors, steel-welded housing IC411, IM B3 Impulse short circuit In the event of a motor short circuit, medium-voltage design in line or converter operation can withstand a peak short-circuit current of 100 kA. Table 3-1 Short-circuit resistance In case of special customer requirements about withstanding impulse short-circuit current, detailed information is needed to offer a solution. Earthing As standard no separate earthing connections (braid) between main terminal box and box adapter are installed. © Innomotics...

3 Main terminal boxes 3.2 Cable entry Cable entry Note Information about cables or the thread size for cable glands must be provided prior to an order. If this information is not available, terminal boxes will be delivered with undrilled cable entry plates. On request the main terminal box with cable glands can be delivered. If anything special is requested, please provide all necessary data for an offer (manufacturer, type, thread size, cable diameter(s), etc.). If cable glands are not included in the scope, cable entries are closed by certified threaded closing plugs. Main cable entry...
