Mixers are widely used in chemical processing, food manufacturing, water treatment, mining, cement and other industrial processes.
In many applications the mixer motor needs to run at different speeds depending on the material, process stage or production requirement.
A VFD on the mixer motor can be used to vary motor speed, provide a softer start and improve process control.
But just because you have the motor power doesn't mean that is the right VFD choice. Also check motor current, mixer load and starting conditions.
1. Check the Motor Nameplate
The first step in selecting a VFD for mixer motor is to check the motor data.
Buyers should provide:
- Motor power
- Rated voltage
- Rated current
- Rated speed
- Frequency
- Motor type
Rated current is especially important.
The VFD rated output current should meet or exceed the motor rated current.
For mixers with heavy starting loads, overload capacity should also be considered.
2. Check the Mixer Load
Different mixers may have very different load conditions.
A mixer handling low-viscosity liquid may start relatively easily, while a mixer handling thick or high-viscosity material may require much higher starting torque.
Before selecting a VFD for mixer motor, buyers should check:
- Material type
- Mixer capacity
- Starting load
- Required speed range
- Working hours
- Starting frequency
3. Choose the Suitable RENLE VFD
After confirming the motor and mixer conditions, buyers can choose the suitable VFD.
For low-voltage mixer motors, the RENLE RNB2000 Low Voltage Variable Frequency Drive can be considered.
The RNB2000 is designed for industrial applications including mixers, conveyors, compressors, pumps, centrifuges and fans. It supports both asynchronous motors and permanent magnet synchronous motors and provides open-loop and closed-loop vector control options.
For mixer applications requiring stronger starting torque or stable operation at low speed, vector control can provide better motor control than basic V/F control.
4. Prepare These Details Before Quotation
To receive a faster and more accurate VFD for conveyor motor recommendation, buyers should prepare:
Motor power, rated voltage, rated current, conveyor length, belt speed, starting load, working hours and installation environment.
If the project requires PLC communication, remote control, braking resistor, bypass cabinet or other accessories, these requirements should also be confirmed before quotation.
5. Simple Selection Process
The selection process can be summarized as:
- Check the motor nameplate.
- Check the conveyor load.
- Confirm the starting torque requirement.
- Select the VFD according to motor voltage and current.
- Choose the suitable RENLE VFD model.
If you need a VFD for conveyor motor, send RENLE your motor nameplate and conveyor operating information. Our engineers can help recommend a suitable VFD model and configuration for your project.
