Application of integrated servo motor in automatic coffee grinder

In modern society, coffee has become an indispensable part of people's lives. To meet the pursuit of taste and quality by coffee lovers, fully automatic coffee grinders have emerged. As a key component, integrated servo motors play an important role. This article discusses the application of integrated servo motors in fully automatic coffee grinders, as well as their advantages and effects.

01. Introduction

An integrated servo motor is a new type of device that combines a motor, driver, and controller into one unit. In fully automatic coffee grinders, integrated servo motors are used to control the grinding process, achieving precise grinding effects and adjustments.

During the grinding process, the integrated servo motor can precisely adjust the speed and spacing of the cutting tools according to the set grinding fineness. During the dosing process, the motor controls the amount of coffee beans through precision sensors, ensuring consistent coffee concentration for each brew. During the brewing process, the motor drives the water column to produce a uniform flow of hot water, allowing the coffee beans to be fully immersed.

02. Application Solution

A certain brand of fully automatic coffee grinder uses a 4-in-1 servo motor that integrates four functions: bean grinding, dosing, brewing, and stirring. A customer (a technology company) adopted a 750W integrated servo motor with a 10:1 reducer. By adjusting the analog voltage through a rotary knob, the motor speed is controlled to automate each operational step.

• Motor Model: PMM8075B

Advantages of Integrated Servo Motors

• High integration improves equipment portability: Integrates brushless motors, drivers, encoders, and controllers into a single unit, significantly reducing equipment size and weight while simplifying wiring and reducing potential failure points.

• Flexibility to meet diverse needs: Supports CAN/CANopen/Modbus communication, allowing flexible control and adjustment according to different work requirements.

• High-precision positioning improves measurement accuracy: High positioning accuracy enables precise positioning of mobile equipment.

• Multiple control modes: Supports PP, VM, PV, PT, HM, IP, CSP, CSV, CST standard modes, as well as NiMotion position mode, speed mode, and torque mode.

• High-speed response improves equipment efficiency: Fast response speed enables quick adjustment of equipment angle and position, improving work efficiency.

• Comprehensive alarm function: Power-on self-diagnosis can detect hardware faults in a timely manner; equipped with multiple safety protection functions including overvoltage/undervoltage, overheat, overcurrent, and stall alarms. LED flashing alarm intuitively displays the current status of the motor.
