Safety Regulations: Core Risks and Protection Requirements

Safe operation is the primary focus emphasized in the document, and multiple types of risks and mandatory protective measures have been identified based on the characteristics of the motor

（1） Electrical safety risks

Voltage hazard: When the motor rotor rotates, the terminal voltage can reach up to 300V, and direct contact can cause electric shock accidents.

Operating standards:

All electrical operations must be carried out after the motor has completely stopped, and only certified electricians are allowed to operate;

Strictly follow the EN 50110-1 (DIN VDE 0105-100) standard, and before operation, follow the five step process of "power-off - isolation - electrical testing - grounding short circuit - shielding adjacent live parts";

Unauthorized modification of electrical circuits or shielding layers is prohibited to avoid short circuits or electromagnetic interference.

（2） Permanent magnet safety risks

Magnetic field hazard: The motor rotor is equipped with high magnetic flux density permanent magnets, which have strong attraction to ferromagnetic objects and can interfere with pacemakers and damage electronic data carriers (such as hard drives, USB drives, magnetic cards).

Protective measures:

It is explicitly prohibited for users of pacemakers to enter the motor disassembly area, and conspicuous signs must be posted on site;

Electronic data carriers should be kept away from the motor (especially the disassembled rotor), with a minimum safe distance of no less than 1m;

During transportation or storage, avoid close contact between the motor and ferromagnetic objects such as iron tools and steel to prevent component damage caused by adsorption and collision.

（3） Thermal safety risk

High temperature hazards: The surface temperature of the motor during operation can reach up to 140 ℃. Direct contact can cause burns, and high temperatures may damage adjacent temperature sensitive components such as wires and electronic components.

Protection requirements:

Do not touch the high-temperature surface of the motor, and install anti touch and anti protective covers if necessary;

Temperature sensitive components should be kept away from the surface of the motor to avoid direct contact;

Ensure the effective operation of the motor temperature control device to prevent damage to windings and bearings due to overheating, or demagnetization of permanent magnets.

（4） Environmental and installation safety restrictions

Prohibit the use of motors in explosion-proof areas (unless specially certified by Siemens);

During the installation, transportation, and maintenance of the motor, it is necessary to avoid severe impacts to prevent permanent magnet displacement or winding damage;

The maximum weight of the motor is 50kg, and lifting devices that comply with Appendix I of the 98/37/EEC Machinery Directive (such as lifting rings and slings) must be used for handling. It is prohibited for a single person to handle in violation of regulations.

Product Core Information: Attributes, Applications, and Delivery

（1） Core attributes of the product

The 1FK6 series motor is a permanent magnet excitation three-phase synchronous servo motor, with a core design adapted to the "sine current principle motor control pulse inverter". Precise control of speed and torque needs to be achieved through a frequency converter, and direct connection to the three-phase power grid is prohibited (otherwise it will cause winding burnout and permanent magnet demagnetization). The motor adopts self cooling method, compact structure, suitable for high-precision driving and positioning scenarios, and has the characteristics of low noise, long life, and high protection level (IP64).
