ZLTECH Nema16 40mm 24V 100W dc 3000RPM encoder servo motor for 3D printer
DC servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loops system, which is comprised of a motor, feedback device, and servo drive providing important feedback on aspects such as position, velocity or torque.
The output speed of the DC servo motor is proportional to the input voltage, and can realize forward and reverse speed control. The utility model has the advantages of large starting torque, wide speed regulation range, good linearity of mechanical characteristics and regulating characteristics, convenient control, etc., but the service life of the reversing brush will be affected by the wear and easy generation of sparks. In recent years, brushless DC servo motor has avoided brush friction and commutation interference, so it has high sensitivity, small dead zone, low noise, long life and little interference to surrounding electronic equipment.
ZLTECH DC servo motors cover a large range of performance specifications, as many of our DC motors come with feedback options. We offer multiple feedback options, mounting configurations, shaft variations, custom windings and integration with gearing solutions.
ZLTECH DC servo motors offer a torque range of 0.32 Nm to 38 Nm, multiple connector types, IP54 rating, and rated speeds 1500RPM-3000RPM.
ZLTECH DC servo motors are typically utilized in applications that require precision control, such as:
- Robotic arms
- AGV wheels
- Industrial automation equipment
- Printers
- Indexers
- Pneumatic marker
- Labeling machine
- Cutting machine
- Laser machine
- Plotter
- Small Engraving machine
- CNC machine
- Handling device

ZLTECH Nema23 57mm 24V 35W/70W/100W/140W 3000RPM DC brushless motor for engraving machine
A BLDC motor with three coils on the stator will have six electrical wires (two to each coil) extending from these coils. In most implementations three of these wires will be connected internally, with the three remaining wires extending from the motor body (in contrast to the two wires extending from the brushed motor described earlier). Wiring in the BLDC motor case is more complicated than simply connecting the power cell’s positive and negative terminals.
The advantages of BLDC motor:
1. Efficiency. As these motors can control continuously at maximum rotational force (torque). Brushed motors, in contrast, reach maximum torque at only certain points in the rotation. For a brushed motor to deliver the same torque as a brushless model, it would need to use larger magnets. This is why even small BLDC motors can deliver considerable power.
2. Controllability. BLDC motors can be controlled, using feedback mechanisms, to delivery precisely the desired torque and rotation speed. Precision control in turn reduces energy consumption and heat generation, and—in cases where motors are battery powered—lengthens the battery life.
3. BLDC motors also offer high durability and low electric noise generation, thanks to the lack of brushes. With brushed motors, the brushes and commutator wear down as a result of continuous moving contact, and also produce sparks where contact is made. Electrical noise, in particular, is the result of the strong sparks that tend to occur at the areas where the brushes pass over the gaps in the commutator. This is why BLDC motors are often considered preferable in applications where it is important to avoid electrical noise.
We’ve seen that BLDC motors offer high efficiency and controllability, and that they have a long operating life. So what are they good for? Because of their efficiency and longevity, they are widely used in devices that run continuously. They have long been used in washing machines, air conditioners, and other consumer electronics; and more recently, they are appearing in fans, where their high efficiency has contributed to a significant reduction in power consumption.

With alarm functions including overvoltage, undervoltage, overcurrent, overtemperature, illegal hall signal and etc.
Characteristics of brushless motor:
1) The motor is small in size and lighter in weight. For asynchronous motor, its rotor is composed of iron core with teeth and grooves, and the grooves are used to place induction windings to generate current and torque. The outer diameter of all rotors should not be too small. At the same time, the existence of mechanical commutator also limits the reduction of the outside diameter, and the armature winding of brushless motor is on the stator, so the outside diameter of the rotor can be relatively reduced.
2) The motor loss is small, this is because the brush is cancelled, and the electronic reversing is used to replace the mechanical reversing, so the friction loss and electric loss of the motor are eliminated. At the same time, there is no magnetic winding on the rotor, so the electric loss is eliminated, and the magnetic field will not produce iron consumption on the rotor.
3) The motor heating is small, this is because the motor loss is small, and the armature winding of the motor is on the stator, directly connected to the casing, so the heat dissipation condition is good, the heat conduction coefficient is large.
4) High efficiency. Although brushless motor is widely used and has a large power range, the application efficiency of different products is also different. In fan products, the efficiency can be improved by 20-30%.
5) the speed regulation performance is good, for the brushless motor through the potentiometer to adjust the voltage to achieve stepless or gear speed regulation, as well as PWM duty cycle speed regulation and pulse frequency speed regulation.
6) Low noise, small interference, low energy consumption, large starting torque, no mechanical friction caused by reversing.
7) High reliability, long service life, eliminating the need of brushes to eliminate the source of main motor faults, electronic commutator motor heating is reduced, motor life is extended.

ZLTECH 24V-36V 5A DC electric Modbus RS485 brushless motor driver controller for AGV
FUNCTION AND USE
1 Speed adjustment mode
External input speed regulation: connect 2 fixed terminals of the external potentiometer to the GND port and +5v port of driver respectively. Connect the adjustment end to SV end to use the external potentiometer (10K~50K) to adjust speed, or through other control units (such as PLC, single-chip microcomputer, and so on) input analog voltage to SV end to realize speed regulation (relative to GND). The acceptance voltage range of the SV port is DC OV to +5V, and the corresponding motor speed is 0 to rated speed.
2 Motor run/stop control (EN)
The motor’s running and stopping could be controlled by controlling the on and off of the terminal EN relative to GND. When the terminal is conductive, the motor will run; otherwise the motor will stop. When using the run/stop terminal to stop motor, the motor will stop naturally, and its motion law is related to the inertia of the load.
3 Motor forward/reverse running control (F/R)
The motor’s running direction could be controlled by controlling the on/off of terminal F/R and terminal GND. When F/R and terminal GND are not conductive, the motor will run clockwise (from motor shaft side), otherwise, the motor will run counterclockwise.
4 Driver Failure
When overvoltage or over-current occurs inside the driver, the driver will enter the protection state and automatically stop working, the motor will stop, and the blue light on the driver will go off. The driver will release the alarm when the enable terminal is reset (ie, EN is disconnected from GND) or power is turned off. When this fault occurs, please check the wiring connection with motor or motor load.
5 RS485 Communication Port
The driver communication mode adopts standard Modbus protocol, which conforms to national standard GB/T 19582.1-2008. Using RS485-based 2-wire serial link communication, the physical interface uses a conventional 3-pin wiring port (A+, GND, B-), and the serial connection is very convenient.
