A magnetorheological power control motor and control method

Abstract

The invention relates to a magnetorheological power control motor and a control method thereof. The magnetorheological power control motor and the control method. The magnetorheological power control motor is characterized in that one end of a drive shaft 11 is connected with a magnetorheological clutch; a first clutch bearing 13 is fixedly arranged on a clutch housing cap 17; a second clutch bearing 24 is fixedly arranged on a clutch housing 23; one end of a drive front bearing 22 is inserted into the clutch housing 23; one end of an output shaft 7 passes through the first clutch bearing 13; the other end of the output shaft 7 passes through the second clutch bearing 24; a clutch disc 19 is fixedly arranged on the output shaft 7; the front part and the rear part of the clutch disc are provided with a front clutch coil 18 and a rear clutch coil 20 respectively; the clutch housing cap 17 and the clutch housing 23 form a clutch outer housing; the internal cavity of the clutch outer housing is provided with magnetorheological fluid 14; and the control method refers to torque control, speed control and position control. According to the magnetorheological power control motor and the control method, the magnetorheological clutch and a traditional motor are functionally combined, and a technical scheme that a servo circuit and a load circuit are isolated is adopted; and therefore, an electronic servo control system is simplified, the operation is simple and convenient, elements of an electrical control system are also reduced, and the cost is directly reduced.

Description

[technical field] [0001] The invention relates to a magneto-rheological power control motor, which can be widely used in fields required for electric dragging, electric walking, power transmission and automatic control of various power equipment or facilities. [Background technique] [0002] The existing motor products are basically divided into two categories according to the level of control technology, one is the traditional AC motor, DC motor, and various variable speed motors. This type of product has a long history and a wide variety, and basically uses traditional low-voltage electrical appliances as the core components. The other type is stepper motors and servo motors with relatively advanced technology, which are mainly used in technical fields with high precision requirements, such as instruments and meters, numerical control machine tools, CNC equipment and other occasions. These products basically use the following Program control technology with integrated circ...

Problems solved by technology

However, the product structure and drive circuit of the servo motor are complicated, and the servo drive also has the function of a frequency converter, so the manufacturing cost is high; the drive power module directly drives the motor load circuit, which is limited by the current level of the high-power motor; especially the brushes and The commutator is easy to wear, the replacement of components is troublesome, and the maintenance cost is very high, so the market price of the servo motor is much more expensive than the traditional motor; before the actual use of the servo motor, it is necessary to solve the heat dissipation, magnetic isolation, self-locking and movement of the motor Various problems such as lightweight components will be limited by different environmental conditions, and the use, operation and maintenance are more complicated; servo motors are mainly suitable for automatic control equipment with high positioning accuracy (such as numerical control machine tools, CNC equipment, etc.), not applicable Electric drive equipment with low positioning accuracy (such as product assembly lines, large-scale mechanical equipment, etc.); due to high product prices, difficult operation, and high maintenance costs, it greatly affects and limits the promotion and application of servo motors

[0006] With the development of industrial technology, the use environment of motors has also undergone great changes. The market has put forward higher requirements for motor control technology. The production process of manually operating and controlling the operation of motors has gradually been replaced by automation. Many stand-alone The operation control has also reached the level of intelligent technology. The traditional motor can no longer meet the subdivision requirements of market development. The market needs a new type of motor with technological innovation, low cost and intelligence.
