HYBRID STEPPER

A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates indiscrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied. Wide range of Gearboxes also available

brushless motor

BRUSHLESS MOTOR

A brushless DC motor (BLDC) is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes. In such motors, current and torque, voltage and rpm are linearly related. Wide range of Gearboxes also available

pm_stepping_motor

PM STEPPING MOTOR

Often referred to as a “tin can” or“ can stack” motor the permanent magnet step motor is a low cost and low resolution type motor with typical step angles of 7.5 to 15° (48 – 24steps/revolution) PM motors as the name implies have permanent magnets added to the motor structure. The rotor no longer has teeth as with the VR motor. Instead the rotor is magnetized with alternating north and south poles situated in a straight line parallel to the rotor shaft. These magnetized rotor poles provide an increased magnetic flux intensity and because of this the PM motor exhibits improved torque characteristics when compared with the VR type.

ac servo motor

AC SERVO MOTOR

A Servo Motor is defined as an automatic device that uses an error-correction routine to correct its motion. The term servo can be applied to systems other than a Servo Motor; systems that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term servo is used it applies to a 'Servo Motor' but is also used as a general control term, meaning that a feedback loop is used to position an item.

news & events BRUSHLESS DC MOTORS – Why should I choose a brushless motor over a brush motor?

The are many factors that affect the decision to select a brushless motor for a particular application.
A brushless motor, also called linear synchronous actuator, is often used when high reliability, long life and high speeds are required.
The bearings in a brushless motor usually become the only parts to wear out.
These bearings can last thousands of hours depending on shaft load and environmental conditions.
Often in a brush-type motor, the brushes and the commutator become the components determining the motor’s life.
In applications where high speeds are required (usually above 30,000 RPM) a brushless motor is considered a better choice.
As motor speed increases so does the wear of the brushes.
Additionally, at higher and higher speeds it becomes increasingly more difficult to keep the brushes from bouncing on the commutator bars as they transition from segment to segment.
Thus, this brush bounce phenomena often becomes the practical limit of speed in a brush-type motor.
The mechanical switching of brushes on commutator segments often generate objectionable electrical and audible noise.
In these instances a brushless motor can usually sound quieter and provide less of a disturbance to other electric equipment in the vicinity.
In applications where weight and/or size of the motor itself is limited, a brushless motor’s commutation control can easily be separated and integrated into other required electronics, thereby improving the effective power-to-weight and/or power-to-volume ratio achievable by a conventional brush-type motor.
All these benefits have a cost.
A brushless motor package (motor and commutation controller) will usually cost more than a brush-type, yet the cost can often be made up in other advantages.
For example, in applications where sophisticated control of the motor’s operation is required, the electronics necessary for a brush-type motor can typically end up costing about the same as the electronics required to control a brushless motor.
In these instances, a brushless motor clearly has the upper hand.
