Stabilizer weight for REGA P5


My girlfriend bought be a Thorens stabilizer weight for my turntable. She did not no which kind of table I was going to buy at the time. I am worried that the weight of the stabilizer at 1.21 lbs will damage the motor. I have tried it a few times and placed it on top of the album when the platter is up to speed. Seems to run fine. Has anyone with a REGA used this type of product! I just don't want to use it if it is going to burnout my motor. Thank you for any input!
