Geared Servo Motor

THESE GEARED SERVO MOTOR ARE PERMANENT SPLIT CAPACITOR INDUCTION MOTORS. NO BRUSHES OR STARTING SWITCHES ARE EMPLOYED. THE LOW INERTIA SERVO TYPE MOTOR IS SPECIFICALLY DESIGNED FOR SERVO APPLICATIONS REQUIRING RELATIVELY FAST RESPONSE. ITS TWO WINDINGS ARE REFERRED TO AS THE FIXED OR REFERENCE PHASE (RED LEADS) AND THE CONTROL PHASE (BLACK LEADS). IN THE NORMAL MODE OF OPERATION A FIXED VOLTAGE IS IMPRESSED ON THE REFERENCE PHASE AND A VARIABLE VOLTAGE IN QUADRATURE TO REFERENCE VOLTAGE IS GIVE TO THE CONTROL PHASE. THE SPEED AND DIRECTION OF ROTATION THEN DEPEND ON THE MAGNITUDE AND PHASE (+-90 DEGREE) OF CONTROL VOLTAGE. HOWEVER BY USING A PHASE SPLITTING CAPACITOR IT IS ALSO POSSIBLE TO OPERATE THE MOTOR (REVERSIBLY) FROM SINGLE PHASE SUPPLY.

SPECIAL FEATURES :
* COMPACT SIZE.
* LOW OUTPUT SPEEDS.
* QUICK REVERSIBILITY.
* HIGH STARTING TORQUE.
* DYNAMIC BRAKING.
* EASY SPEED CONTROL.
* ABILITY TO WITHSTAND FOR CONTINUOUS STALLED ROTOR CONDITION.

SPECIFICATIONS:
1. Gear Ratio: Motors are available with any one of the following standard gear reduction ratios of 10 30 100 300 1000 3000. (Basic rotor speed is 2500 rpm).
2. Windings: Motor windings are designated by means of two letters. First letter refers to the voltage to the reference phase and the second letter to the voltage on the control phase. The letter code for voltages is as follows: A = 230V B = 115V
C = 115-0-115V D = 23V E = 11.5 F = 11.5-0-11.5.
