摘要：A massaging device includes a motor integrated with a housing, a shaft fortransmitting the motor motion, a treatment head attachable to the shaft. The rotationalspeed of the motor can be measured as part of a control circuit. The rotational speedprovides an actual value to the control circuit. A setpoint of the rotation speed of the
motor can be manually adjusted. The control circuit is designed so that the currentsupplied to the motor is controlled depending on the difference between theinstantaneous actual value and the selected setpoint.
