Simpson delta 402 - NO spin dry?

Firstly there was a strong burning smell when it came to the spin cycle and eventually nothing would happen when it reached this point - no noise & no movement. So I replaced the brake solenoid because the old one was fused and now when the machine comes to the spin dry cycles the solenoid releases the drum and there is a very loud buzzing sound and the mortor moves a little and once spun for a few moments but the motor normally doesn't spin. Is this a problem with the motor? There is no indication of smell that anything is wrong with the motor. The motor works perfectly in the wash cycle.
