Description
Technical field
The present invention relates to bench drill technical field, specially a kind of brushless bench drill of novel permanent magnetic.
Background technique
Bench drill abbreviation bench drill is a kind of compact, easy to operate, is typically mounted on and uses in dedicated
Small-sized drilling processing machine tool.Traditional bench drill generally uses AC induction motor as power motor, is transmitted by tower belt pulley
So that traditional bench drill has the disadvantage that
1, asynchronous machine work is that rotor windings will absorb part electric energy excitation from power grid, consumes power grid electric energy, this part electricity
It can finally be generated heat and be consumed in rotor windings with electric current, which accounts for about the 20~30% of motor total losses, it makes motor
Efficiency reduces, and is in inductance current after rotor excitation current conversion to stator winding, makes to fall behind into the electric current in people's stator winding
In one angle of network voltage, the power factor of motor is caused to reduce.
2, when starting asynchronous motor, it is desirable that motor has sufficiently large starting torque, but wishes that starting current should not be too
Greatly, in order to avoid power grid generates excessive voltage landing and influences to connect the normal operation of other electric machinery and apparatus on power grid.
In addition, when starting current is excessive, the impact for making motor itself be done by excessive electricity power is also made into winding if often started
The danger of overheat.Therefore, the starting design of asynchronous machine is often faced with dilemma.
3, when being worked due to asynchronous machine, rotor windings have electric current flowing, and this electric current is disappeared in the form of thermal energy completely
It consumes, so a large amount of heat will be generated in rotor windings, increases the degree of preventing of motor, affect the service life of motor.
4, because the power factor of asynchronous machine is low, motor will absorb a large amount of reactive current from power grid, cause power grid, writing brush
There are a large amount of reactive currents in transformer equipment and generating equipment, and then decline the quality factor of power grid, has aggravated power grid and rifle becomes
The load of electric equipment and generating equipment.Reactive current is intended to consumption part in power grid, writing brush transformer equipment and generating equipment simultaneously
Electric energy causes electric power network efficiency to be lower, the effective use of electric energy of shadow noon.Also due to the low efficiency of asynchronous machine, will expire
Sufficient writing brush goes out playing for power and asks, and certainly will absorbing electric energy from the power grid more, further increase the loss of electric two energy, having aggravated power grid
Load.
5, rig floor velocity variations are realized by " tower belt pulley ", are merely capable of realizing that the speed of finite progression is adjusted, function
The utilization of the single bench drill limited significantly of energy.
6, traditional bench drill is generally provided only with fixed workpiece clamping table, and conventional workpiece clamping bench only can be realized simply
Lift adjustment, actual processing workpiece as need when drilling on the multiple lateral inclined-planes of workpiece, operation difficulty is big.
Based on this, the present invention devises a kind of brushless bench drill of novel permanent magnetic, to solve the above problems.
Summary of the invention
