Electric Motor (Frameless)
Frameless motors are Compact, lightweight ,Precise in performance , Environmental resilience since they are Embedded directly into the application, frameless motors can be thoroughly protected from caustic washdown fluids, submersion, weather exposure and other environmental hazards.
Two main types of frameless motors that are Frameless outrunner and Frameless inrunner torque motors are in a wide range of diameters, stack lengths and winding variations.
Electric Motor (Gear Motor)
A Geared Motor is a component whose mechanism adjusts the speed of the motor, leading them to operate at a certain speed .
Advantages of the Gear Motor:
- It reduces the speed of the input motor. Micro Motors gear motors have a variety of reduction ratios to select the appropriate speed for your application.
- Availability of multiple combinations of both gearbox and motor at different voltages.
- Having an integrated motor + gearbox solution makes it easier for the end user to develop the machinery and allows him to be able to apply it within his project without wasting time searching for individual parts.
- It is a ready-to-use all-in-one solution that requires no alignment work by the end user.
- Multiplies the torque of the motor. This feature is very important because it allows high torque even in a small space.
Electric Motor (Hysteresis)
Hysteresis Electric Motor can be operated either using a single phase or three phases and in a noiseless operating environment, it maintains a constant speed. The torque generated in the motor is due to the hysteresis and eddy current which is induced due to stator winding.
A hysteresis motor is constructed of five main components:
- Stator
- Single phase stator winding
- Rotor
- Shaft
- Shading coil
There are 4 types of hysteresis motor they are :
- Cylindrical type
- Disk type
- Circumferential-Field type
- Axial-Field type
Electric Motor (Induction)
Induction motors are categorized into two main types: single-phase and three-phase induction motors.
Single-phase induction motors are designed to operate from single-phase supply and are manufactured in large quantities for use in:
– Pumps
– Compressors
– Small fans
– Mixers
– Toys
– High-speed vacuums
– Electric shavers
– Drilling machines
There are four types of single-phase induction motors:
– Split phase induction motor
– Capacitor-start induction motor
– Capacitor-run induction motor
– Shaded pole induction motor
Electric Motor (Linear)
Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. In a linear motor. The rotor with permanent magnets becomes the stationary part of the linear motor (also called the secondary, or magnet plate), and the stator, which contains the coil windings, becomes the moving part (also called the primary, or coil unit). to direct and improve the magnetic flux interaction between the primary and secondary components ,Magnetic Tracks will be sued .
Different linear motors can be constructed for wide applications , these liner motors are :
– Low Acceleration Linear Motors
– High Acceleration Linear Motors
– Synchronous linear motors
– Induction linear motors
– Homopolar linear motors
– Tubular linear motors.
– Piezoelectric linear motors
Electric Motor (Permanent Magnet DC )
In PMDC motors, the armature rotates due to a mechanical force induced by the magnetic field when current flows through its windings, according to Fleming’s left-hand rule.
The PMDC motor features a simple design with a stator that houses permanent magnets and an armature with windings and a commutator.
PMDC motors are efficient and cost-effective as they require no external power for field excitation and have fewer parts, making them compact.
These motors are ideal for low-power applications where complex speed controls are unnecessary, such as in toys ,commonly used as a starter motor in automobiles, windshield wipers, washers, blowers used in heaters and air conditioners ,computer disc drives and in many more.
Electric Motor (Piezoelectric)
Conversely, the application of an electric field enables certain materials to alter their shape or size. Piezoelectric motors utilize this dynamic ability to generate motion. piezoelectric motors generate motion through the physical deformation of piezoelectric materials. Due to their one-of-a-kind operation, piezoelectric motors are optimal for applications that require precise positional control since they are able to produce motion that is both very precise and controllable at a smaller scale.
Materials such as quartz, Rochelle salt, and synthetic crystals such as lead zirconate titanate (PZT) are used to manufacture piezoelectric elements, which are the fundamental components of piezoelectric motors. These elements, when exposed to an electric voltage, undergo controlled deformation, enabling them to convert electrical energy directly into mechanical energy.
Piezoelectric motors stand out for their ability to maintain their position even in the absence of power, only using energy when necessary for movement.
Electric Motor (Self-Excited DC )
Series Wound DC Motor
In series-wound DC motors, the field winding and the armature coil are connected in series to the power supply. This means the same current flows through the coil and armature. Since these types of motors can work both with DC and AC, they are also called universal motors. Series motors always rotate in the same direction, and their speed depends on the mechanical load. Series-wound motors are used in electric locomotives, electric trams, hoists, cranes, and other applications where high torque at low speeds is required
Electric Motor (Separately Excited DC )
The armature winding is powered by DC voltage V via a commutator and brushes, which causes the flow of current I. As a result of the magnetic field and the current, a force is acting on the armature, which starts rotating. The purpose of the commutator is to ensure the current flow through the relevant parts of the armature windings, so that the force acting on the armature is maximum.
Separately Excited Dc Motors have a broad range of output voltage and can function in stable conditions with any field excitation.
Electric Motor (Series Wound DC )
Characteristics of Series Wound DC Motors are high starting torque , simple in construction , cost effective and high power density .
Applications of Series Wound DC Model Motors:
- Electric Vehicles: Electric scooters, golf carts, and light rail vehicles due to their high starting torque.
- Construction Equipment: Due to their ability to handle, Cranes, hoists, and winches utilizes series wound motors.
- Trains: Series wound motors make them a common choice for powering model train locomotives due to their cost effective and simplicity.
