Abstract
An advertising display including a display object, a motor connected to the display object for rotating the object about a rotation axis, and a control circuit coupled to the motor. The control circuit includes a direct current energy source, and an oscillator connected to the energy source for generating a predetermined series of regularly timed energy pulses having a selected frequency and duty cycle to cause excitation of the motor in response to the energy pulses.
Claims19
An advertising display comprising:
- a display object including advertising material;
- a motor for rotating said object about a rotation axis at a varying velocity and having a housing and a drive shaft rotatably supported by said housing and drivingly connected to said display object;
- and
- a control circuit coupled to said motor, the control circuit being adapted to be connected to a direct current energy source, and including an oscillator connected to said energy source for generating a predetermined series of regularly timed energy pulses having a selected frequency and duty cycle to cause excitation of said motor in response to said energy pulses.
An advertising display comprising:
- a display object including advertising material;
- means for supporting said display object for rotation about an axis, said means including a motor having a housing and a rotor shaft rotatably supported by said housing and connected to said display object;
- and
- rotating means for rotating said object about said axis at a varying velocity, said rotating means including a control circuit coupled to said motor, the control circuit being adapted to be connected to a direct current energy source so as to generate a predetermined series of regularly timed energy pulses having a selected frequency and duty cycle to cause excitation of said motor in response to said energy pulses.
An apparatus comprising:
- a housing;
- a shaft rotatably supported by said housing;
- an advertising display object connected to said shaft and including advertising material;.
- an electric motor coupled to said shaft for rotating said shaft about an axis;
- and
- control circuit means for sequentially energizing the motor to cause rotation of the display object at a varying velocity and for providing an alternating electrical signal to said motor, said signal having a selected frequency and a selected duty cycle.
A method of displaying an object including advertising material, said method comprising the steps of:
- (A) providing an object including advertising material;
- (B) providing a motor having a housing and a rotor shaft rotatably supported by said housing for rotation about an axis;
- (C) connecting said object to said rotor shaft;
- (D) generating a predetermined series of regularly timed energy pulses, said pulses having a selected frequency and a selected duty cycle;
- and
- (E) energizing said motor with said predetermined series of regularly timed energy pulses so as to rotate said object about said axis at a varying velocity.
