OJ Electronics<\/small>Patented drive solution<\/h2>\n
\n

The DRHX drives have a self-cooling design, eliminating the need for additional cooling, such as fans. The gear-free technology ensures accurate control throughout a broader range of speeds. Our patented sensorless software monitors the rotation of the rotor, which means that no physical\/optical rotor guard is required. This gives you a simple, efficient solution, and with fewer components, you also get an easier installation.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n

Rotor<\/small>Field oriented sensor­less motor control<\/h2>\n
\n

Combining a high-torque stepper motor with a closed-loop sensorless control gives you more accurate, energy-efficient control. The drive regulates the current to the exact level required to achieve the right speed and torque. Patent granted.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

Rotor<\/small>Rotor Constant Speed<\/h2>\n
\n
<\/div>\n

OJ DRHX Constant Speed lets you master the new technology of a stepper motor in the most basic way. The setting is either on or off. You\u2019ll typically use these drives in simple cooling\/ventilation systems. When on, the motor will run on one of four predefined speeds. It is a cost-efficient solution when you do not need a demand-driven application.<\/p>\n

The drives cover from 1 Nm to 8 Nm.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n

Rotor<\/small>Rotor with Modbus Control<\/h2>\n
\n

With RS-485 control, the drive can both send and receive information. This provides you with advanced control, allowing the recovery of energy from the air to be adjusted as required.<\/p>\n

This solution is often used in an AHU system. The user interface provides visual information to the user via et triple colour LED<\/p>\n

Covers from 1 Nm to 8 Nm.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n

Rotor<\/small>Rotor with Modbus &<\/span> Analogue Control<\/h2>\n
\n

Modbus and 0-10V control leave you with all options of advanced control and optimization of energy consumption and air quality. A 3×7 segment display provides user information of actual performance and error messages.<\/p>\n

This solution is perfect for advanced AHU systems and refurbishment.<\/p>\n

Covers from 1 Nm to 14 Nm<\/p>\n<\/div><\/div>\n<\/p><\/div>\n
