Mechatronic drive system in elevator doors

elevator

Maxon brushless DC motors and encoders drive lift doors open and closed.

Schindler is a well-known manufacturer of elevators and lifts, moving more than one billion people every day. When we take the lift, we press the button, the cab arrives, we enter and disembark at the desired floor. What is a simple event has alot of technology in the undertaking – in the elevator shaft, motor chamber, control box and in the lift compartment itself.

A motor installed in the cab opens and closes both the doors of the cab and the doors at each particular floor. The requirements of the motor are very specific: small yet powerful, reliable, energy-saving and intelligent. Maxon developed two Door Drives alongside Schindler, using a brushless DC motor with a diameter of 90 millimeters, a MILE encoder combined with the motor and a customised EPOS2 positioning controller. With two power levels, the more powerful version uses a belt drive and is able to move doors weighing up to 400 kilograms. The smaller and latest version is more compact and moves doors weighing up to 120 kilograms.

Encased in a housing, the Door Drive can be mounted directly onto the lift cab. And this is where its real work starts. The ability to adapt to the many different types of elevators, with differently sized cabs, different materials and, depending on the country, different safety standards. After a calibration procedure, the controller of the Door Drive detects the size and weight of the doors, autonomously calculates the optimal parameters corrects them if necessary and drives the doors open and closed.

586137_mmc_ESCON_Module_50-8_HE_450px

For applications withstanding tough environments particularly suited to defence, marine, aerospace, scientific research and oil & gas industries.

Excessive humidity, condensation and airborne pollution can cause corrosion, reduce surface resistance, and trigger metal migration. maxon’s new DC servo motor controller is not affected by these conditions, due to the polymer-coated circuit board. Even silicon or lubricant oils do not stick. The controller withstands ambient temperatures from -40 °C to +92 °C. The vibration and shock endurance comply with the high requirements of the Environmental Engineering Considerations & Laboratory Tests (MIL-STD 810F).

This results in a wide range of applications in fields like defence, marine, aerospace, scientific research, oil refineries and automotive systems.

Available to order online from May onwards, the DC motor controller is designed for both brushed and brushless (with Hall sensors) DC motors up to 400 W of continuous power and 750 W of peak power. The Servoamplifier has configurable digital and analogue inputs along with current limits and speed ramp settings.

DC motor and harmonic gear zero backlash450px

 

New levels of torque and position capability are now possible with the development of adaptive hardware for maxon low profile brushless DC motors and harmonic planetary gearheads.

Pictured is a combination showing the maxon brushless DC 70W 24V motor, 2048 counts per turn internally integrated encoder and the new harmonic light weight low profile zero backlash gearhead. The gearmotor assembly increases the torque and reduces the size of previous solutions using planetary gearbox technology. The output capability is 19Nm repeated and 31Nm intermittently, which is ground-breaking for a combination just 55mm diameter and 59mm long for all three components. Having and internal encoder and a zero backlash gear makes the unit ideal for robotic joint and positioning applications in industrial automation, process control and also for precision laboratory and scientific equipment.

New motion controller design for speed and position control of DC motors

EPOS4_24_1.5_450px

maxon motor’s new motion controller for DC motors is very small indeed. Just 17g and 39mmx54mm the position controller can also control both brushed DC motors and brushless DC motors (BLDC motors).

Available on request is the newest version of the successful EPOS DC motor control modules, the EPOS4 24/1.5. The tiny dimensions of the controller belie it’s capabilities. It retains the full motion control capabilities of much larger controllers including RS232, USB, CanOpen and EtherCAT communications onboard or via adaptor modules. Feedback from the DC or BLDC motor is achieved using either hall sensors, incremental encoders or absolute encoders. It can be used with current / torque control, closed loop speed control and position control. Designed primarily for use on 12V or 24V systems the controller is based on a very high PWM frequency of 100kHz for adaption with highly dynamic ironless and coreless DC motors that have low inductance levels. Current limiting, overcurrent, over temperature, under voltage, overvoltage and short cct protective functions are all included as standard. Free setup software for auto configuration and tuning of motors is supplied along with programming examples for PC, PLC, Labview and Linux environments. IEC61800-5-2 based Safe Torque Off (STO) also makes the controller suitable for use in critical applications such as manufacturing processes and collaborative robotics.

DC motors steering the rear wheels of race cars.

 

Active rear wheel steering drivetech

Maxon actuators, DC motors, gearheads and encoders help to improve the handling and overall driving stability of a race car through rear wheel steering, with up to 3 degrees transfer per side.

A maxon supported Young Engineers Student project is developing mechatronics for steering the rear wheels of a race car. At the heart is a maxon spindle drive (linear actuator) that converts rotational movement into linear movement. Fitted with an EC-4 pole brushless DC motor to provide up to 200W of power, GP32 planetary gearhead for torque and two maxon EPOS2 position controllers with HEDL encoders to set the steer angle of the wheels. The maxon drive system is connected to the cars internal controls to calculate the desired steer angle.

The main issues for the engineers were lightweight, small components, with enough force to set the required steer angle and trustworthiness of the components to work reliably without fail.
