What is the optimal clearance distance for motor brakes?

[VonCamila]

The function of motor brake pads is to achieve the braking action, with a typical clearance of 0.7mm. The maximum clearance should not exceed 1mm, as this may easily cause motor burnout. In practical applications, it is best to appropriately reduce the clearance according to actual needs to achieve precise braking positioning. Generally speaking, the smaller the clearance, the better the braking effect, but the greater the wear. The essential tool for adjusting motor brake pad clearance is a feeler gauge. More relevant information is as follows: 1. Adjustment: The method for adjusting the clearance of motor brakes involves a spring on the motor clutch handle. Tighten the outer screw; if this still doesn't work, there is a brake pad distance adjustment screw beneath the spring. First loosen the inner fixing screw, then tighten the outer long screw. 2. Working principle: The working principle is that when the motor is powered, the DC current in the coil generates suction to separate the two friction surfaces at the tail, allowing the motor to rotate freely. Conversely, the motor is braked by the spring's restoring force. Depending on the motor's power, the coil resistance ranges from tens to hundreds of ohms.
