Ensure that your end product conforms to all currently valid legal requirements. Follow the compulsory national, local and installation-specific regulations. Starting up the motors is not permitted until the end product conforms to this stipulations of the named guidelines. Observe the SIEMENS Project Planning Instructions for 1PM6 motors. The safety instructions must be observed during the transport, storage, assembly, disassembly and operation of the hollow shaft motors! Failure to observe the instructions can lead to serious personal injuries or property damage. All activities (transport, storage, assembly, disassembly of the hollow-shaft motors) must be performed by qualified, skilled workers who are aware of the specific dangers and who observe the stipulations of the present operating instructions. Maintenance (replacement of the gear encoder or bearing) may only be performed by the manufacturer or authorized SIEMENS service centers. Mechanical hazards Appropriate tools etc. are used for transport and assembly work Lifting devices, ground conveyors and lifting tackle must correspond to the valid regulations, e.g.: EU Directive for Machines 98/37 EC, appendix 1 Regulations of the statutory industrial accident insurance institution BGV D6, BGV D8, BGV D27, VBG 9a ecc. There is an injury hazard in the vicinity of the rotating motor. The manufacturer of the end product is responsible for protection against accidental contact with the rotating motor. Do not wear any additional clothing, jewelry or allow long hair to hang freely. Electrical hazards The electrical connection to the hollow shaft motors is made as described in the operating instructions. All electrical work only must be performed by qualified electricians and always with the equipment electrically dead. Requirements of qualified electricians according to EN 50110-1:1996 (DIN VDE 0105-100): - Knowledge of electrical engineering - Experience of electrotechnical work - Knowledge of the plant / machine - Knowledge of the hazards and safety measures - Ability to decide upon a safe working sequence. Hollow-shaft motors are only driven with configured converters. Any other connection can lead to their destruction. Never connect the motors directly to an external three-phase mains! The correct phase sequence is vital. The temperature sensor and encoder system including electronics contain electrostatically endangered components (EEC). Do not touch the connections with your hands or with tools which could be electrostatically charged! Thermal hazards The surface temperature of the motors may exceed 80oC (176oF). Do not touch hot surfaces! Temperature-sensitive components (electric lines, electronic components) must not touch hot surfaces. Intended Usage The motors correspond to the harmonized standards of the EN 60034 (VDE 0530) series. They are intended for industrial or commercial plants. Special case: More stringent requirements must be taken into consideration during the configuration and assembly for use in non- commercial plants. Usage for the intended purpose includes observing all the specifications in the operating instructions. Ambient temperatures: -15oC to +40oC (5oF to 104oF). Site altitude: of up to 1000 m a.s.l. The conditions at the location of use must correspond to all the information on the rating plate. It is forbidden to use them in areas at risk of explosion. The operating instructions are part of the scope of delivery and shall be kept in an accessible place. The technical details of special versions and design variants of the motors can vary. Please contact the manufacturer or a SIEMENS service center if you have any questions regarding the use or operational characteristics of the motors. 2 Product information 2.1 Application range The hollow shaft of the motor serves for the supply of cooling lubricant or the insertion of collets. The motors are used when the environmental conditions enable the use of air cooling. Application cases: Milling machines with full encapsulation, turning lathes with driven tools or counterspindles. 2.2 Technical parameters Motor types 1PM6 101, 103, 105, 107 1PM6 133, 135, 137, 138 Types of construction Fig. 1 PM1 hollow-shaft motors are optionally fitted with either radial ventilation or axial ventilation. Standard protection class IP54 Ambient temperature max. 40oC Measuring-surface sound-pressure level (EN 21 680 Part 1) approx. 70 dB(A); 72 dB(A) with L37 Balancing as per EN 60034-14 vibration severity grade SR The bearings are designed for high speeds: Motor types Standard L37 1PM6101...105 12.000 min-1 18.000 min-1 1PM6107 12.000 min-1 15.000 min-1 1PM6133 10.500 min-1 15.000 min-1 1PM6137 10.500 min-1 13.000 min-1 1PM6138 10.500 min-1 12.000 min-1 2.3 Mode of operation and design Motors of the 1PM6 series are water-cooled, four-pole asynchronous motors. The squirrel-cage rotor (rotor) has a hollow shaft. Main subassemblies - Core-and-winding assembly Temperature sensor for temperature measurement and regulation, and to protect against overheating, fitted in the stator winding (a second sensor as a reserve). - Encoder system Incremental encoder sin/cos (I-256) for measuring the motor speed and the relative change in the rotor position (installed at the ND-end). - Separate fan set 2CW83.. according to figs. 2.1 and 2.2 (three-phase, external-rotor motor), arranged axially or radially (top or on the side). 2.4 Transport, Storage All the lifting eye-bolts provided (Fig. 2) should be used during transport. Do not attach any additional loads. Examples of standards: EU Directive for Machines 98/37 EC, appendix 1. WARNING Danger during lifting and transporting procedures. Improper handling, unsuitable or defective devices, tools etc. can cause injuries and/or property damage. Lifting devices, floor conveyors and lifting tackle must conform to the currently valid regulations. Siemens AG 4 WARNING Hazard from rotating rotor! Provide the output elements with protection against accidental contact. Safety rules for working in electrical installations according to EN 50110-1:1996 (DIN VDE 0105-100): - De-energize before starting work - Isolate from uploads/S4/hollow-shaft-motors-1pm6-air-cooled.pdf
