HySecurity MX000691, MOTOR BRUSH & SPRING KIT SCOTT
HySecurity MX000691 is a motor brush and spring kit commonly described as a set of four carbon brushes and four springs for select 2HP DC motors used in HySecurity gate operators. Motor brushes maintain electrical contact with the commutator inside a brushed DC motor. When brushes wear down, the operator may lose torque, arc excessively, run intermittently, trip protection, or fail to start consistently. This kit is a maintenance and repair part for compatible brushed DC motors; it is not used on every HySecurity motor. Verify the motor horsepower, motor type, and parts diagram before ordering. If a motor has commutator damage, bearing noise, overheating, or winding faults, brushes alone may not restore reliable operation.
