Description

Noise reduction cooling formula machine controller

Technical Field

The invention relates to the technical field of motor controllers, in particular to a noise-reducing and temperature-reducing motor controller.

Background

The motor controller is an integrated circuit which controls the motor to work according to the set direction, speed, angle and response time through active work. The simplest motor controller is a switch that connects the motor to a power source, such as a small household appliance or power tool. The switch may be operated manually or the motor may be automatically started or stopped using a relay or contactor connected to some sensor. The switch may have different selectable positions to allow the motor to be connected to the power source in different ways, which may include reducing the voltage at the start of the motor, reversing the operation, or selecting different speeds. Small controllers may omit overload and overcurrent protection devices, where external overcurrent protection circuitry is used to prevent excessive current flow, and small motors have built-in overload protection, which automatically opens to prevent overload. Larger motors may incorporate overload or temperature sensing relays in the controller, and fuses or circuit breakers to protect the machine from overcurrents, and may also include limit switches or other devices to protect the machine.
