As a matter of fact, it is rather difficult for people to analyze the operation characteristics of three-phase brushless motor accurately. Motor air gap flux density distribution along with the air gap by sinusoidal. When the winding is energized, magnetic flux generated by the current impact of the air gap is negligible. In the condition of the switch operation, the power transistor is constant pressure drop. Each winding is symmetry and the corresponding circuit is completely consistent. The relevant electric time constant can be neglected. The power of sensored brushless motor and others that control circuit are also negligible. Three-phase brushless DC motors are also synchronous motors. It is very important to protect the three-phase brushless dc motor drivers.

Basics of an Electric Hub Motor

There are two main types of electric bike motors, each with their own set of features and functions.

The hub motor:
• The motor is compact in size to fit into the wheel.
• Most hub motors provide great efficiency with relatively low noise.
• Many of the leading companies offer custom-made hub electric bike motors to fit the needs of the consumer.
• Initially, you have to set up the built-in programmer.
• The best models offer cruise control.
• The weight can range from 5-15kg, which is a lot.
• The power ranges from 250-1000 Watts depending on the hub motor regulations for the area.
• The price ranges from a $100 to as much as $500.
• It is extremely energy efficient with minimum loss of energy and the total cost of maintenance is surprisingly low.
• Generally, you have to modify the wheel to make room for the electric bike motor.

The brushless motor:
• The electric bike motor has electronic functioning.
• It is environmentally safe.
• The motor works with a DC current.
• Generally, a brushless motor has an integrated gearbox, which significantly increases the amount of motor torque.
• High speed cruising with this motor is a highly enjoyable experience.

If you intend on buying an e bike kit then it will come with one of these motors and probably a choice between wide ranges of power. E bike kits are easier to install for a first time user and a person with limited knowledge of machinery. However, if you want to construct an entire electric bike from scratch, then you should pay special attention to the electric bike motor specifications to select the kind that would fit your lifestyle.

Whether you are interested in purchasing an ebike or you’re looking into starting from scratch in order to create your very own customized electric bicycle, you will definitely need to know the basics of the electric bike motor.

BLDC motor

Reluctance that the magnetic flux through the steel, air gap and magnet composed of magnetic circuit of the degree of difficulty. Magnetic flux is a very good source, the equivalent current source. Phase winding MMF is a good source, a voltage source. At low magnetic load, steel reluctance is small, and not in magnetic saturation. In high magnetic loading (typically> 1.5 T), the reluctance of steel will start with the rapid increase in magnetic saturation. Air has a very high reluctance, it has nothing to do with the magnetic load. Magnetic materials have similar characteristics.

Reluctance with the position change, so can be used as the basis of sensor operation. In all the BLDC motor, the reluctance of some changes will occur with the point of view. From the motor point of view, the reluctance of change and change in inductance as obvious. Reluctance variation has obvious advantages, because at zero speed can be detected. However, you need to know to control the motor L (i, θ) characteristics.

Unfortunately, for many BLDC motors, reluctance changes with location is too small, can not be reliably measured. Especially for surface mounting of the magnet motor, the large effective air gap, so this feature in this type of motor has been particularly evident. Therefore, the reluctance of the main part of the same, which makes the remaining changes occurred with the location is difficult to measure. In specially designed for low torque ripple of the motor, the reluctance changes will be small because of the reluctance change will produce extra torque. Magnetic or magnetic motor hidden inside the angle changes with great reluctance, but they are generally powered with sinusoidal voltage and therefore not be discussed here.

Motor BEMF waveform changes with position and velocity. It is not possible at zero speed and low speed with the BEMF detection position. However, there are many applications (such as fans and pumps) at low speed or position control loop does not need to run. For these applications, BEMF method is very suitable. There are many ways to use BEMF, the main method can be summarized as follows:
• The motor terminal voltage detection
- By direct measurement or estimated (state and DC bus voltage switching is known).
• midpoint voltage detection
- Applies only to special characteristics of Y-connection BEMF motor.
- Does not really need the first four lines. Using the resistor network and differential operation, you can re-establish the center of a star connection.
• bus current gradient detection
- Because of the change go hand in hand ahead of or behind the rotor change, bus current thus depends on the particular shape.
- Can not use the fast bus current control.

Just what is an electric bike? Basically it is an everyday bicycle with a battery powered electric motor attached, recharged by plugging it into the electricity mains. It is very simple, once you start to pedal the motor kicks in, stop pedaling the motor cuts off; pedaling speeds of up to 25kmph can be reached with the aid of the motor. Electric bikes are perfect for those who want to keep or get fit, for short distance or city centre commuting, those who have no wish to drive and active older people.

hub motor and Pump motor

hub motor armature speed transfer of thousands, and are excited (or series wound) motor, the rotor and the stator has a coil, there are still large in the low speed torque. Pump motor is an asynchronous induction motor, the stator with coils only, of course, the rotor can also be seen as a coil, but not with copper wire, and not low speed, 1,400 rpm, a 4-pole motor.

hub motor is a generic type (string-excited) motors can be common in the AC and DC power to run.

Series wound AC motor and DC motor structure is no different, such as hair dryer, mill, hub motor, and so used the motor, but did not like the DC motor with permanent magnets to generate magnetic fields. A commutator, carbon brushes, work with electric spark generated noisy. AC induction motors in general no commutator, carbon brush, the input current from the stator windings.

1, hub motor is what kind of motor?

hub motor is a series wound motor, features a brush, working in a spark, noise; torque is larger, does not require phase-shifting capacitor.

2, with the structure of the DC series motors are identical, of course, is not the same coil winding.

3, series motor is the specified sub-coils and the rotor excitation coil is in series. This heavy motor load, the current increase, the excitation current is also large, strong magnetic field generated by the torque will also increase, so a larger starting torque.

4, as mentioned earlier, AC and DC current through the coil impedance varies greatly, 220V DC 220V AC motor with a large coil is not the same, can not be universal.
