The optimal operating temperature of the GSA87-YEJ2.2KW reducer (gear reduction + electromagnetic brake motor) must simultaneously meet the three dimensions of the reducer case body temperature zone, oil temperature, and motor body temperature . The core is oil temperature as the primary control indicator.
1. Optimal operating temperature (stable operating conditions)
1. Temperature zone (core) of the reducer case
Optimal range : 50℃～70℃ (shell surface)
Oil temperature (oil pool) : 40℃～60℃ (optimal, balance of lubrication and heat dissipation)
Temperature rise control : oil temperature ≤ ambient temperature + 30℃ ~ 40℃ ; shell ≤ ambient temperature + 25℃
2. YEJ2.2KW motor body (Class F insulation)
Stator winding : ≤ 105℃ (F-class insulation allows temperature rise of 105K, upper limit is 145℃ when the environment is 40℃)
Chassis/Bearing : ≤ 70℃ (warm to the touch but not hot)
Brake : ≤ 80℃ (to avoid overheating of the brake coil and failure)
2. Temperature upper limit (safety warning, not allowed for long periods of time)
Oil temperature: ≤80℃ (if it exceeds, the oil film will fail and accelerate aging)
Shell: ≤85℃ (short-term peak value ≤90℃)
Motor winding: ≤145℃ (when the environment is 40℃)
3. Effects of too low temperature (<40℃)
The viscosity of the lubricating oil increases sharply, the fluidity is poor, the gears/bearings are insufficiently lubricated, and the wear is increased.
Large starting resistance, low efficiency, and easy overloading of the motor
