A shallow test is recommended to insure proper operation of the motor and MWD tool. It is also recommended to run a float on top of the motor to prevent damage to the motor. Some Crescent motors incorporate a top sub bored for a float, otherwise a float sub will be provided. When tripping in the hole, it is recommended to break circulation periodically especially if heat is a factor. Pressure readings should be recorded for reference later if any problems should occur. To start the motor, avoid dropping or ‘spudding’ the motor on the bottom of the hole. Start circulating a few feet off bottom and raise the flow rate to recommendations of the particular motor. Apply weight gradually to achieve optimum differential pressure. Do not exceed specified maximum differential pressure. The motor may stall if the power demand exceeds the output of the motor. If the motor stalls while sliding, immediately shut off the pumps, pull the motor off bottom, and restart. If the motor stalls while rotating, shut down the pumps and rotary immediately, pull off bottom, and then restart. Prolonged stalling will damage the power section. When the motor run
)1. Regenerative brake frequency represents the frequency of the motor's stops from the rated speed with deceleration without load. . If the load is connected, frequency will be defines as 1/(m+1), where m=load moment of inertia/rotor moment of inertia. . When the motor speed exceeds the rated speed, regenerative brake frequency is in inverse proportion to the square of (running speed/rated speed). . Power supply voltage is AC230V (at 200V of the main voltage). If the supply voltage fluctuates, frequency is in inverse proportion to the square of (Running supply voltage/230) relative to the value in the table. . When regeneration occurs continuously such cases as running speed frequently changes or vertical feeding, consult us or a dealer. 2. If the effective torque is within the rated torque, there is no limit in generative brake. 3. Consult us or a dealer if the load moment of inertia exceeds the specified value. 4. Specified releasing time is obtained with the use of surge absorber for brake (Z15D151 by Ishizuka Electronic or equivalent). ( ) represents the actually measured value using a diode (200V, 1A or equivalent)
