Introduction: At present, there is also a new type of motor connector called micro motor connector, which is a servo motor connector that combines power supply and brake into one. This combination design is more compact, achieves higher protection standards, and is more resistant to vibration and shock.
It can be seen from the development trend of motors that no matter what type of motor it is, it is now equipped with more and more functions, and at the same time, it emphasizes a compact design in terms of volume. With more functions, the amount of data involved continues to increase, so it is crucial to achieve the highest possible motor speed with an absolutely reliable transmission connection. Different motors have different requirements for connectors.
First, let’s look at servo motors , a type of motor that is becoming increasingly popular due to its ultra-high efficiency. In material handling systems and robotics applications, servo motors are gradually replacing hydraulic systems by integrating a variety of controls. On this type of motor, circular and rectangular connectors are the most widely used. Hybrid connectors also have many applications, including micro-motor connectors, heavy-duty connectors, and more. It can be said that the servo motors have corresponding connectors from the inside out to help.
Linear motors highlight a need for low friction and high flexibility. The application of connectors in this type of motor is not complicated. The main requirement is to ensure reliability and achieve fast connection.
Spindle motors can be said to be the core of modern production systems, with high requirements for precision and reliability. This type of motor application requires precise control and reliable feedback in harsh industrial environments, so a hybrid connector system is preferred for this type of motor application. Of course the necessary circular and rectangular connectors are also the basis for flexible connection of such motors.
To talk about the compact design of the motor, the stepper motor is definitely a new force in the compact design at low cost. The demand for standard plastic rectangular interconnect connectors for this type of cost-sensitive motor is enormous, and the choice of connectors is biased towards standardization. It favors standardized connections over flexible connector combinations.
What the trend of highly compatible modular motor connections brings
Modularity is a trend that the entire connector system is upgrading, and this is no exception in motor connections. This is evident in the electrical connectors in the motor connector category, where electrical connectors are beginning to move towards having only a few single parts with a modular architecture, which makes them highly compatible and available in many different combinations are available.
Quick locking is one of the prerequisites for the highly compatible modularization of connectors. The rotatable connector housing or connector shield terminal can quickly and reliably connect the modular connector system together through quick locking, which is connected at the motor interface. is extremely common in . The motor interface connector needs to adjust the input and output of power, which is not only in industrial scenarios, but also in any motor application scenarios where the performance of the connection system is tested. The two difficulties of high vibration and high noise are frequent visitors in industrial scenarios. .
Modularity brings a high degree of flexibility to the motor connection that needs to connect power, signal, data or a combination of the three, which saves a lot of space for the miniaturized design of the motor. The rotatable female terminal on the motor can realize more convenient and flexible cable connection, and the connection is no longer limited by the angle. Meeting the compact design requirements of the motor is certainly no problem.
More importantly, performance. On the basis of flexible connection, how to reliably make the drive motor, spindle drive and servo motor reach high speed, and can easily handle start and stop operations. This requires connectors capable of delivering high voltages and currents continuously. The voltage-carrying capacity and current-carrying capacity of the connection system depend entirely on the technical strength of each manufacturer. There is no uniform standard for the electrical performance of a single connection or a hybrid connection with custom shielding.
In addition, in the familiar M8/M12 circular connector field, the development trend of high conductivity and high bandwidth does not need to be repeated.
What surprises does the micro motor connection bring?
There is also an emerging motor connector, called a micro motor connector, which is a servo motor connector that combines power and brakes into one. This combination design is more compact, achieves higher protection standards, and is more resistant to vibration and shock.
This miniature motor connector is mainly used in power, brake, and encoder, and this hybrid connector distributes the cost of motor connection lower. Compared to standard plastic connectors, miniature motor connectors allow for quick installation and locking from the wire end to the motor socket end. On the premise of saving a lot of space, it can still reach the IP67 protection level, which is suitable for motor applications in harsh environments.
The signal of the micro motor connector varies from 2-16 bits, for brakes, it is usually 2 bits; for power, it has 6 bits; for encoder or signal connectors, it has 9 bits. The combination of power supply, brake, and encoder can be combined arbitrarily, and the choice of micro-motor connectors is full of flexibility. For compact servo motors, this type of connector will bring more and more surprises in the future.
Summary
More and more compact motor designs are demanding more and more interface connections. The simple truth is that when the internal data and various interfaces can be connected quickly, reliably and efficiently, the working efficiency of the motor will increase, and the energy efficiency will also increase. Connectors play an increasingly important role in assisting motors to achieve high-performance operation control.
