▲OZ Systems BLDC motors and drivers

Established in 2007, OZ Systems Co., Ltd. (www.oz-sys.com) is a robot parts company that manufactures BLDC motors and drivers.

OZ Systems has localized [domestically produced] the production of BLDC motors and drivers that can be applied to industrial robots and are being used by Dream Robot, manufacturers of orthogonal robots, and Nsquare, manufacturers of unmanned transporting robots. They have received reliability certification in the market, and are selling and actively conducting marketing activities to the country’s major companies. They are also actively promoting exports of their products.

The company’s main products are their BLDC motors, BLDC drivers and decelerators. The BLDC motors are divided into speed control and position control types. The speed control types comprise the OZBM60 Series and OZBM42 Series.

▲OZBM60 Series

The OZBM60 Series is a motor with a 60mm-sized hall sensor and a speed of 300- 3000RPM. Depending on the Rated Output Power, there are three models: 20, 40 and 60. The OZBM42 Series is a 100W motor with a speed control range of 300 to 4000 RPM. The company offers a Rated Output Power 100 model.

▲OZBM42 Series

In the control type, the company offers the OZBM60 series, the first BLDC motor for position control using a built-in encoder. Depending on the Rated Output Power, three models are offered: 13, 26, and 40.

The BLDC driver is also classified into speed control type and a position control type.

▲OZBV-10A series

For the speed control type, the OZBV-10A series is available. This product features: △ Easy driver control of the host controller by applying MODBUS-RTU communication protocols. △ Supports RS-232 or RS422 communication method. △ Easy modification, saving, and monitoring of the driver parameters by using the OZBV-exclusive GUI. △ Testing of the motor and driver by using only GUI without using the host controller or separate switch wiring. △ Motor control through acceleration/deceleration and GAIN adjustment. △ Up to 8 speeds can be selected and controlled using external sensor signals or digital input signals. △ Supports 4 kinds of OZBV driver control methods (RUN / STOP, CW / CCW, communication control, speed index control).

▲OZBP-05A

For position control type, the OZBP-05A series is available. The features of this product include: △ Easy driver control of the host controller by applying MODBUS-RTU communication protocols. △ Supports RS-232 or RS422 communication method. △ Easy modification, saving, and monitoring of driver parameters by using the exclusive GUI. △ Testing of the motor and driver by using only GUI without using host controller or separate switch wiring. △ Motor control through accelerator/ decelerator and GAIN adjustment. △ Simple PTP (Point-To-Point) operation possible with 8 position values built into the driver, without motion controller. △ Total of 8 positions can be stored in the driver; up to 16 can be set through program modification.
