Mainly used for equipment with strict requirements for driving accuracy and response speed, including:

Machine tools (cutting, machining centers);

Automated production equipment;

Industrial robot;

Material handling devices (such as conveyors, robotic arms).

（3） Delivery scope and acceptance requirements

Delivery list: motor body (including integrated encoder, optional brake), separate product nameplate (to be attached near the equipment for reference), multilingual manual;

Acceptance criteria:

After receiving the goods, it is necessary to immediately verify the waybill with the physical object to confirm that there are no missing parts or transportation damage;

If any transportation damage is found, it is necessary to immediately claim compensation from the carrier; If there are component defects or incomplete deliveries, it is necessary to promptly contact the responsible representative of Siemens;

The instruction manual should be properly stored in an easily accessible location near the equipment for easy operation and maintenance reference.

Installation and Connection: Specifications and Key Requirements

（1） Transportation and Storage Standards

Transportation requirements:

Use appropriate lifting devices (such as slings and rings) to avoid tying the motor shaft or flange directly with ropes and prevent damage to components;

During transportation, it is necessary to fix it firmly, avoid severe bumps or impacts, and prevent the permanent magnet from shifting;

Comply with local transportation regulations, clarify that the motor is a "strong magnet containing equipment", and avoid magnetic interference issues during air transportation.

Storage conditions:

The storage environment needs to be dry, low dust, and low vibration (effective vibration speed)v eff<0.2mm/s）；Avoid direct sunlight or high temperature and humidity environments to prevent the winding from getting damp or the performance of the permanent magnet from deteriorating;

Before storage, remove the rust inhibitor at the shaft end (using commercial solvents) to avoid affecting subsequent installation.

（2） Mechanical installation requirements

Installation gap: At least three sides of the motor need to reserve a 100mm heat dissipation gap to ensure self cooling effect;

Fixed specifications:

Use hexagon socket head screws with a strength grade of ≥ 8.8 to fix the flange, and tighten them evenly (to avoid flange deformation);

The screw torque must meet the equipment requirements, and excessive tightening is prohibited to cause thread damage;

Load limit:

Motors with integrated brakes are prohibited from bearing axial forces, and radial forces must strictly follow the requirements of the project planning guidelines;

When installing vertically (with the shaft end facing upwards), protective measures should be taken to prevent liquid from seeping into the upper bearing;
