Other Motor Control Considerations
The drive electronics for the BLDC motors are integrated into the motor itself, all that needed is a power supply with the sufficient voltage and current.
Key Things to Remember
The pump is not a pressure holding device. An external check valve is recommended, if there is a pressure holding requirement.
Pump orientation does not affect performance or life.
Pulse Width Modulation (PWM)
Pulse-width modulation is a commonly used technique for controlling DC motors.
1.The average value of the voltage fed to the motor is controlled by turning a switch between the voltage supply and the motor on-and-off at a fast pace. The longer the switch is on compared to the off time, the higher the power supplied to the motor.
2.The PWM switching frequency varies for different types of devices, and is selected based on how it affects the device. For example, Some applications require a faster switching frequency to reduce the noise or electrical noise that is being heard.
3.The term duty cycle describes the ratio of on-time to the period (one complete on-and-off cycle). Duty cycle is normally expressed as a percentage of on-time, 100% being full-power and 50% being half-power.
4.The advantage of PWM is the reduction of power-loss due to switching versus other control methods. We recommends controlling the pump using 15kHz - 20 kHz frequency range.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
