Roots type blower is a positive displacement blower, also know as rotary lobe blower, tri lobe blower, twin lobe blower, rotary piston blower, roots pump, roots compressor etc.
As gas blower, it need to be anti-corrosion and/or anti-explosion based on different gas. So the treatment will be different for different gas. Currently, for gas blower or called gas booster, piston ring seal, mechanical seal for anti-explosion, stainless steel material and/or Ni-p coating and/or Teflon coating for anti-corrosion.

*High Torque to inertia ratio&up to 25000Nm/kgm²
*Fast dynamic response, time constant

KYDBL4875-2E is an intelligent brushless DC dual-motor controller. The brushless dual-motor driver can control two brushless DC motors at the same time. It adopts 32-bit high-performance MCU and advanced movement processing algorithm to realize internal electric differential function. The controller uses the Hall signal inside the motor as the rotor position feedback and works with the external incremental encoder (1000â??2500 line) signal to control the movement of motor, realizing speed open-loop, close-loop modes, position mode and torque mode. It has two-way independent driver chip, two-way encoder processing chip, two-way Hall signal processing chip. Meanwhile, it has multiple failure alarm functions. It has two working modes: independent mode and mixed mode.
Independent mode: It can realize fully independent control of two-way motor, and the control signal part is controlled by two-way input signals. Two-way brushless DC motor can control the speed and direction of motor, separately.
Mixed mode: It can realize the synchronous control (forward, backward, left and right rotation) of two brushless motors.
The control signal has as many as 8 modes (wireless remote control, rocker, potentiometer, analog quantity, frequency, pulse width, RS232, CAN bus).
* Wide-range voltage input, 10-55V, max 60V.
* Intelligent PID control loop.
* Working mode: Speed open-loop, close-loop control, torque close-loop control, position close-loop control.
* External potentiometer, 0-5V analog quantity or pulse command control mode, RC (pulse width signal outputted by the receiver of aeromodelling remote control) control mode.
* Safety forward & reverse control, four-quadrant operation, support regeneration.
* Enable control function.
* Maximum current control.
* 4-way input port; the function can be defined as analog input, pulse input or digital input functions.
* 6-way digital (MOS tube open-drain) output, which can serve as the failure alarm status output of controller and can control the external relay to realize actions such as automatic disconnection of power.
* Abnormalities like overcurrent, overheating, overvoltage and short circuit will start the protection function.
* LED status indicator.
* CAN bus communication, see the detailed communication protocol when using it.
* RS232 communication, see the detailed communication protocol when using it.
