A look back: maxon DC motors in analogue tape recorders.

Analogue TR 1977

1977: The Commodore PET computer is first sold; Atari released its Video Computer system; The Porsche 928 is unveiled at the Geneva Motor show; and Uher-Werke released the SG 630 hi-fi tape recorder (with 4 maxon DC motors inside).

In the late ‘70s, maxon motor were consulted for their innovative DC motors for use in a hi-fi tape recorder. Two brushless DC motors operated the shaft that drove the tape head mechanism. What was considered 39 years ago to be cutting edge technology, was the two maxon DC motors that drove the large 27cm spools of tape. One motor constantly pulled the tape and the second motor slowed the tape down to avoid tangling the ribbon. The “new” ironless windings were praised for having low inertia compared to conventional motors of the time. A servo-gearhead motor was used for the “Omega-loop” of the tape to record the audio. In a few short years, this equipment was superseded by digital technology and eventually dropped off the market altogether. Maxon DC motors are still used in high-end record players, such as the Kronos, that has two maxon DC motors in the turntables.

Tailoring the perfect custom DC gear motor solution.

Cropped pic 450px

This robust right angle DC servo gear motor example showcases maxon motors capability to supply unique solutions for demanding applications. Supplied into Australia’s defence industry the motor and gearing needed to be of the most robust and efficient design.

The system is comprised of an 40mm rare earth brushless DC motor fitted with a 42mm 66:1 ceramic planetary reduction gearhead, a right angle 5:1 helical bevel reduction gearhead and a 500cpt digital encoder. The combination is specifically assembled to provide the exact proportion of speed and torque within a fixed shape the motor needs to fit within. The reduction ratio split between the two gearheads needs to be carefully selected in order to focus the high speed and low torque power transmission function on the ceramic planetary gearhead utilising the advantages of a gearhead containing high wear resistant ceramic components. The low speed high torque transfer task is conducted by a large low ratio helical bevel gear train. This design gearbox contains a very large tooth section by comparison to the planetary gearhead making it more suitable for this task. maxon motor’s 40mm rare earth motor gives high levels of power without the negative influences of a laminated stack within the motor. This coreless, ironless design allows for zero cogging movement and accurate motor control at low speeds for precision positioning control.

Oh yes, any colour as long as its black.

DC servo linear actuation – made to order.

DC_Servo_Linear_Actuation_495px

This long ball screw linear actuator driven by a DC servo motor and gearhead is the latest example that shows maxon motor’s ability to provide tailored solutions. Recently supplied by maxon motor in Australia, the unit is made of a high grade stainless steel ball screw, integrated thrust block bearing system, planetary gearhead and DC servo motor.

With a mechanical positioning accuracy of 0.037mm, a 133mm/s linear speed and a rating of over 1000N of mechanical intermittent force over its 600mm length, the device is compact and powerful. The bearing system allows both push and pull at the same rating and maxon are able to manufacture the unit with a linear length to suit the application. Electrically driving the ball screw with a detent free DC servo motor allows the movement of the load to be controlled precisely and smoothly. Based on the pitch of the ball screw and the positioning resolution required, the DC motor can be fitted with high resolution digital encoders and can be controlled with either full position controllers or servo amplifiers within a position control loop. This example is being used with current control of the DC servo motor giving a proportionally controlled force over the movement range. With adjustability of the motor winding, gearhead ratio, actuator pitch and travel length a combination of components can be specified to give the most compact and appropriate servo system.

EPOS4_interview

 

For more than 25 years maxon motor have focused on motion control of brushed and brushless DC motors, evolving from stand-alone functionality to complete integrated drive systems.

Long gone are the days of placing a DC motor to run by itself in an application. Developments in technology, diagnostics, networking and efficient safety have contributed to the evolution of basic motor functionality to present-day complete small systems. To one end, maxon motor offer simple current & speed controllers and at the other end are controllers for high-performance torque, speed or position control as well as motor integrated devices. The new EPOS4 controller, released in April 2016, stands out from every other maxon DC motor position controller before it because of the controllers ability to achieve maximum power density in very small spaces. There is also the option to program the EPOS4 via various interfaces allowing for a tailored DC drive system that furnishes optimum coordination of the individual components. It also negates the need to possess intricate knowledge of brushed and brushless DC motors.
