Moog CD series compact dynamic brushless servo motor

2. Customization capability

Moog provides deep customization services to meet the needs of special scenarios:

Winding customization: Customize winding parameters based on customer supply voltage (such as non-standard DC 400 V) and speed requirements (such as ultra high speed 15000 r/min), and optimize torque speed characteristics.

Mechanical customization: Customize shaft length, diameter (such as hollow shaft, spline shaft), flange size (such as adapting to customer equipment installation holes), and even frameless (no shell) design, integrated into customer motion mechanisms.

Environmental adaptation: High temperature coating (able to withstand temperatures above 200 ℃), explosion-proof design (ATEX II 3G), radiation resistant version, suitable for extreme environments such as aerospace and nuclear industries.

Feedback customization: Supports multi turn absolute encoders (such as Heidenhain EQN series), Hall sensors, or integrated speed generators to meet high-precision multi turn positioning requirements.

Selection and Application Guide

1. Core dimensions for selection

Load matching: Select the model based on the load inertia (recommended load inertia/motor inertia ≤ 5:1, high dynamic scenario ≤ 1:1), continuous torque, peak torque requirements, and motor torque speed curve (such as the G-4-M8 model with a continuous torque of 8.31 Nm at 3500 r/min).

Voltage and driver adaptation: The low voltage version (325 V) is suitable for small and medium power drivers, while the high voltage version (565 V) is suitable for high-power and high-speed scenarios, ensuring that the DC bus voltage of the driver matches.

Feedback accuracy: For general positioning, choose a Resolver (anti-interference), while for precise positioning, choose an absolute encoder (such as a 13 bit single loop+12 bit multi loop, with a resolution of 4096 × 4096).

Environmental parameters: IP67 shaft seal should be selected for humid/dusty environments, and the temperature resistance level of the winding should be confirmed for high temperature environments. Explosion proof certified models should be selected for hazardous areas.

2. Typical application scenarios

Industrial robots: G-2-G-4 models are used for robot joints, with low inertia supporting fast start stop and high torque density reducing joint volume;

Semiconductor equipment: G-1~G-3 models are used for wafer transfer robotic arms, with low cogging torque to ensure low-speed stability and IP67 protection suitable for clean room environments;

Precision machine tools: G-4~G-6 models are used for spindle or feed axis, combining high torque and high speed to meet high-precision cutting requirements;

Testing and simulation: The G-5~G-6 models are used for aerospace simulators, with high dynamic response and high reliability to support complex motion simulations.

Key points for installation and maintenance

1. Installation specifications

Mechanical installation: The flange needs to be fixed on a steel mounting plate of ≥ 300 × 300 × 25 mm (to ensure heat dissipation), and the axis alignment error should be ≤ 0.1 mm (to avoid excessive radial load);

Electrical connection: Separate the power line (U/V/W) from the signal line (feedback/braking) to avoid electromagnetic interference; The brake power cord needs to be supplied separately to prevent brake failure after the driver is powered off;

Heat dissipation design: Natural cooling motors require a reserved heat dissipation space of ≥ 50 mm, while forced air cooling motors must ensure that the fan inlet is unobstructed (fan voltage 24 VDC, current 1 A).

2. Maintenance suggestions

Regular inspection: Check the bearing noise and shaft seal sealing every 6 months, and shorten it to 3 months in high temperature environments;

Temperature monitoring: Monitor the winding temperature through the driver to avoid exceeding 110 ℃ for a long time (when the ambient temperature is 40 ℃);

Spare parts management: It is recommended to use spare brakes and bearings for key equipment, and Moog provides original factory maintenance services to ensure the shortest downtime.

Order Information

Model coding rules: For example, "G-4-V8" represents G-4 base, high-voltage version (565 V), and 8th stack length (corresponding to continuous torque of 8.31 Nm);

Standard accessories: including motor cables, installation screws, feedback interface manual. Customized models require information on load inertia, speed, environmental parameters, etc.
