Overview
YBBP series fameproof varlable frequency speed regulation three-phase asynchronous motor ls opened by our company accordingto market demand. The new product is used together with the inverter to achieve smooth and stepless speed regulation in a widerange. Speed range, dynamic response, speed regulation accuracy, low frequency torque,slip compensation, power factor,efficlency,etc. It has great advantages in meeting the explosive gas miture of coal, petroleum and chemical industries. place. The explosion-proof performance of the motor comples with GB3836.1- -2010 "Explosve environment Part 1: Equpment General Requirementsand GB3836.2-2010 "Explosive Environment Part 2: Protected by Flameproof Enclosure d" The provislons of the equipment.
Scope of Application and Operating Conditions
1. Scope of Application
1.1 Ambient air temperature varies seasonally, generally not exceeding -15 to +40°C;
1.2 Ambient atmospheric pressure: 80 to 110 kPa;
1.3 Altitude not exceeding 1000 meters;
1.4 Maximum relative humidity of ambient air not exceeding 95% (at +25°C);
1.5 Underground mining work areas in coal mines where explosive hazards exist due to combustible gases, vapors, mists, dust, or fibers mixed with air within the upper and lower explosive limits.
2. Electrical Conditions for Motor Operation
2.1 Frequency conversion range: 5–50 Hz for constant torque speed control, 50–100 Hz for constant power speed control.
2.2 Motor rating is continuous duty, with duty type S1.
2.3 The motor stator windings employ an F-class insulation system. When operating at minimum airflow within specified conditions, the bearing temperature (measured thermometer method) shall not exceed 95°C, the maximum surface temperature of the housing (measured thermometer method) shall not exceed 150°C, and the stator winding temperature rise (measured resistance method) shall be evaluated at 85K.
