Micro DC Servo Drives

SEA1-80A Micro Dc servo drives boast an extremely compact size and high power density. This egg-sized drive can continuously output up to 5600W of effective power. It features a sampling frequency of 10kHz, 6 digital inputs, and 2 digital outputs. Its rich interface supports almost all encoder feedback, including incremental and absolute dual feedback, as well as resolver and absolute dual feedback.

The SEA1-80A Micro Dc servo drives can be applied to almost all fields. Its ultra-small size, ultra-high precision, ultra-high current capacity, and strong versatility are the advantages that the SEA1-80A drive brings to the product.

This is a motion control solution from JINGYUE Technology based on SEA dc servo drive and an 8mm flange servo motor, which has been widely used in die bonders.

The SEA DC servo drive employs a DSP+FPGA architecture, which endows the product with unparalleled high-speed response and powerful data processing capabilities. We used a Renishaw laser interferometer to test the control accuracy of the SEA DC servo drive, and the results show that the SEA DC servo drive performs excellently.

The SEA series of DC servo drives currently includes square series 1-80A, 140A, 210A; and ring series C49, C68, C81 (with hollow outer diameters of 49mm, 68mm, and 81mm respectively).

Product Parameter(Specification)

The rated currents of the SEA1-80A DC servo drive are 1A, 3A, 6A, 10A, 15A, 25A, 50A, 70A, and 80A (80V).

The rated voltages are 100V and 80V. However, we recommend that you use the rated supply voltage to power the driver, and that the maximum supply voltage should not exceed the values

in the table.

The voltage and current figures mentioned above refer to the voltage and current of the power supply bus. In reality, the voltage and current reaching the phase lines will be less than the values

at the bus line.

When selecting a drive product, the parameter "effective continuous current" must be taken into account.

The maximum continuous output power of the SEA1-80A is 5.6 kW.

Product feature And Application

We describe the SEA1-80A drive product with the following characteristics:

1. Extremely small size, only the size of an egg.

2. Very high power density, supporting DC motors up to 5.6KW.

3. Extremely high control precision, supporting feedback from almost all mainstream encoders. Supports incremental + absolute dual feedback, and resolver + absolute dual feedback.

4. 10KHz current sampling frequency, high bandwidth, high linearity, and high response.

5. Wide range of applications.

It can be applied to almost all industries. For applications requiring precise motion control, the SEA1-80A is particularly well-suited.

The DC servo drive has been widely used in the embodied intelligence industry. A well-known Chinese manufacturer of robotic wolves has purchased and used the SEA1-80A DC servo drive in its robotic wolf products.

In the field of medical devices, SEA 1-80A DC servo drive products are used in surgical robots, exoskeletons, and biochemical testing equipment.

In the field of integrated circuits and semiconductor equipment, the SEA1-80A is used in wafer handling, dicing machines, die bonders, probe stations, and placement machines. JINGYUE TECHNOLOGY's SEA series products are also widely used in radar turntables, motion simulation, photoelectric tracking equipment, and shaftless pump pushers. We are a core supplier to 90% turntable manufacturers in China.

Product structure and process

SEA 1-80A dc servo drive consists of five parts: a power module based on an aluminum-based heat sink, a drive module, a control module, a communication module, and an interface board.

We outsource our surface mount technology (SMT) work to well-known SMT factories. We inspect each layer of the PCB to ensure the SMT semi-finished products are intact. Then, we assemble, rivet, and solder the power board and driver board, and inspect them again. Only the semi-finished products that pass the inspection proceed to the next process, where the control board is installed and soldered onto the assembly module.

This means that our products undergo a total of 12 inspections from a single PCB to the finished product. These inspections are not random checks, but mandatory checks.

The products also need to undergo aging tests, extreme temperature tests (if necessary), pre-warehouse testing, and pre-shipment testing.

The power supply and motor wiring method is determined based on the current. If the current is less than 25A, we use quick-connect ports. If the current is greater than 25A, I solder wires for the customer.

We provide our customers with the necessary cables for product debugging.
