Abstract
A massaging device includes a motor integrated with a housing, a shaft for transmitting the motor motion, a treatment head attachable to the shaft. The rotational speed of the motor can be measured as part of a control circuit. The rotational speed provides 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 current supplied to the motor is controlled depending on the difference between the instantaneous actual value and the selected setpoint.
