New product release! Ultra-small servo all-in-one machine is now on pre-sale! PMM28 series integrated servo motor
.webp)
With the continuous development and deepening of integrated drive and control motors, automation products are penetrating into all areas of production and life with unprecedented breadth and depth. Among them, small integrated motors, such as 28-step and 35-step motors, have been widely loved by users since they were launched on the market due to their small size. They are often seen in industries such as experimental instruments, electronic appliances, precision manufacturing and medical equipment.
However, due to the motor properties and size limitations, the speed and torque of small stepper motors are relatively low. For example, most applications of 28-step motors need to be used at 1000rpm, and the torque must be limited to a certain value (such as STM2832B at 0.05Nm and STM2851B at 0.1Nm).
Based on the pain points and needs of high torque and high speed, we have carried out technical research and development and design improvements on the 28mm integrated motor, and upgraded it to the PMM28 servo series based on the STM28 series stepper products. The new product has been further improved in terms of speed, torque, etc., and can meet users' wider application needs.
Let's take a look at the features and functions of the upgraded product!
01. Highly integrated design, simplified installation and maintenance
PMM28 series integrated servo structure diagram
The PMM28 series integrated servo motor follows a highly integrated design concept, integrating a permanent magnet synchronous motor, encoder and servo driver. Its compact body is not only the ultimate pursuit of space utilization, but also a perfect interpretation of modern technological aesthetics.
This design not only greatly simplifies the system structure, but also significantly improves the overall operating efficiency. For users, this means that there is no need to worry about the matching between the drive and the motor during installation and deployment, thereby reducing deployment difficulty and cost.
For example, the PMM2802 model has a body length of 6.6 cm and a width of 2.8 cm. This integrated design not only reflects the ingenuity of product design, but also brings unprecedented convenience in actual use. When you gently place it in the palm of your hand, you can immediately feel its delicacy and lightness. It seems to be tailor-made for users who pursue extreme portability. It is just the right size.
The above parts together constitute the PMM series integrated servo motor. Overall, in terms of appearance, it is stable and beautiful.
02. Larger load torque to meet diverse needs
Compared to our previous STM28 series, the PMM28 series has a significant improvement in load torque.
The larger load torque enables this series to easily cope with various complex working conditions, and can maintain stable performance output regardless of overload or high-speed movement.
Therefore, the PMM28 series integrated servo motor can meet the needs of high speed and high load capacity in many fields such as precision machining, experimental instruments, electronic appliances and medical equipment.
03.CANopen/RS485 bus communication
PMM28 series integrated servo motors support optional CANopen and RS485 bus standard communication protocols. They can be quickly and easily integrated into various industrial automation systems to achieve seamless connection and efficient collaboration with other equipment.
CANopen, as a widely used network communication protocol, provides a stable and reliable data transmission channel for motors with its high real-time performance, high reliability and strong scalability. The RS485 bus, with its long transmission distance and fast transmission speed, provides strong support for the application of motors in industrial sites.
04. Multiple motion control modes
PMM28 series integrated servo motors not only support basic motion control functions, but also provide multiple advanced control modes of CiA402 such as profile position mode (PP), profile velocity mode (PV) and origin return (HM). It provides users with a more flexible and precise motion control solution.
The support of these advanced control modes enables the integrated servo motor to adapt to the needs of various application scenarios and realize efficient and reliable industrial automation control.
05.Configurable DI and DO
The PMM28 series integrated servo motors specifically support the configuration of DI (digital input) and DO (digital output) functions, providing users with powerful control flexibility and convenience of system integration.
In terms of DI, the PMM28 series provides 3 input ports that support pulse input. Users can directly connect external pulse generators through the ports to achieve precise position or speed control.
At the same time, these DI ports are also highly programmable, allowing users to configure them into different functional modes according to actual needs, including but not limited to enable control (used to start or stop motor operation), positive and negative switches (control the forward and reverse rotation of the motor), origin switches (used to set or confirm the origin of the mechanical position), alarm reset (clear the error state during motor operation), pause function (temporarily interrupt motor operation) and multi-segment operation instructions (preset multiple motion trajectories to achieve complex motion control).
In terms of DO, the PMM28 series is equipped with 2 output ports, which also support flexible configuration options. Users can configure these DO ports as ordinary digital output ports according to system requirements to transmit status signals or control other devices.
In addition, DO ports are often configured as motor running/stop status indication, target position arrival signal output and alarm output. The latter can issue an alarm in time when the motor is running abnormally to ensure production safety.
For more configuration and usage instructions, please refer to the User Manual and Communication Manual.
06. Host computer debugging software, easy operation
PMM28 series integrated servo motors support NiMStudio host computer software debugging. This debugging software has an intuitive and friendly interface and powerful functions, making the debugging and operation process of integrated servo motors easier and faster.
Through the software, users can easily perform communication tests, support CANopen and RS485 communications; support parameter reading and writing, and can set various parameters of the motor, including motion speed, position, etc. Support control mode operation, including CiA402 and NiMotion modes to meet the needs of different operating scenarios; support cloud upgrades, including studio software upgrades, configuration file upgrades, historical version downloads, firmware upgrades, device description file downloads, and restore factory parameter file downloads.
At the same time, the software also provides real-time monitoring functions, which can display the working status and performance data of the motor in real time, helping users to find and solve problems in a timely manner.
Therefore, with the help of this host computer debugging software, the debugging and deployment process can be faster and more efficient, and can meet more complex and changeable industrial automation application needs.
