Represents the medium-to-large power range, with an estimated power output of 0.75kW–3kW.

2. Core Parameter Code: 30270

This code encompasses critical specifications such as speed, torque, and encoder resolution.
For example, it may indicate:

Rated speed: 3000 rpm
Rated torque: 2.7 Nm
(Actual values depend on the full parameter set.)

3. Configuration Fields: 0/1/00/00/00/00/00

These digits define additional options, including but not limited to:

Voltage level
Protection rating (e.g., IP65)
Communication protocol (e.g., EtherCAT, CANopen)
Functional add-ons (e.g., brakes, oil seals).

Besides the above features, the hollow cup motor also has some other advantages. For example, the hollow cup motor can achievehigh precisionposition control, can provide a higher torque density, and is more flexible in design. These features make the hollow cup motor very popular in many application fields.However, hollow cup motors also have some limitations. First, the output power of hollow cup motors is limited, and they are mainly used for low-power applications. Secondly, due to the particularity of the structure, the manufacturing cost of hollow cup motors is relatively high. In addition, the driving andcontrol circuits of hollow cup motors are also relatively complex, and they have high technical requirements forengineers.In summary, the hollow cup motor is a type of motor that is different from ordinary motors. Its compact structure, high efficiency, fast response, high axial rigidity, and low noise and vibration make the hollow cup motor widely used in many application fields. However, the hollow cup motor also has some limitations, and the appropriate motor type needs to be selected according to the specific application scenario.
