Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few servo motor, ac servo motor manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom servo motors, ac servo motors has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

The MAC series of brushless servo motors with integrated electronics is a major step forward. All the necessary electronics in a servo motor system are integrated in the servo motor itself. A traditional servo motor system has in the past typically been based on a central controller unit placed away from the servo motor. This circumstance has the negative effect that the installation cost is a major part of the total expenses in building machinery. The basic idea in the MAC servo motors is to minimize these costs but also to make a component that is much better protected against electrical noise which can be a typical problem when using long cables between controller and servo motor. The servo motor, hall effect sensor, encoder and electronics are specially developed by JVL so that they together form a closed unit where the power driver and controller is mounted inside the servo motor in a closed section.

The advantages by this integrated servo motor solution are: De-central intelligence. Simple installation. No cables between servo motor and driver. EMC safe. Switching noise remains within servo motor.
Single or dual supply. Compact. Does not take space in cabinet. Typically a 3/5 core cable is used from PLC or similar to MAC motor. 24 or 48VDC power for MAC50-141, 115/230V for MAC800. Low price. Interface possibilities with the MAC servo motor: From PC/PLC with drive commands via RS232/RS485/RS422. Pulse/direction or quadrature inputs. 10 bit (MAC50-141), 12bit (MAC800) ±10V input for speed or torque control. A+B encoder output. Register mode via 4 inputs or serial commands
Option for nano PLC built-in with grafical programming tools. Option for Fieldbus. ProfibusDP, Canbus, CANopen, Devicenet, Ethernet, Wireless. Multiaxis operation with up to 255 units on the same 460Kbit RS485 bus.
