Abstract

The invention provides a DC electric driver and electric equipment including the DC electric driver. The DC electric driver is used to drive the electric equipment, and comprises a DC motor, a DC power source, an instruction sending part, an output sensor, a controller, a driving unit and a chopper; and the DC electric driver is characterized in that the DC motor is composed of 2j armature winding branches independent from each other, 2j*m commutator segments connected to windings and 2j brushes independent from each other, connected with the chopper and making contact with the commutator segments, each armature winding branch is composed of m windings, the chopper is a single-tube chopper and includes j chopping units independent from each other, the DC power supply comprises of j power supply units independent from each other, each power supply unit is connected one chopping unit and one brush in one to one correspondence and supplies power to the armature winding branch connected with the corresponding brush, and each of j and m represents a positive integer not lower than 2.

Description

technical field [0001] The invention belongs to the field of direct current motors, in particular to a direct current electric drive device and electric equipment including the direct current electric drive device. Background technique [0002] With the increase in the number of days and duration of smog in major cities, the country has become more and more strict on the exhaust emission management of fuel equipment; in addition, in a closed indoor working environment, the use of fuel equipment is prohibited; in addition, oil as an energy source It is non-renewable and will face depletion in a few decades. Therefore, electric equipment using electricity as an energy source, such as electric vehicles, electric forklifts and other electric equipment, is more and more favored by manufacturers and consumers. Not only does it have low pollution, it can provide electric energy through renewable energy, and compared with fuel equipment, it also has the advantages of high energy ut...
