Motor System Enables Elevators to Ride Smoothly

Many factors have contributed to the fact that in the past five years, home elevator sales have doubled. These include the aging of the affluent baby-boom generation. In the next five years, an estimated 70 million people will be of retirement age; many of them will be looking at retaining their independence by staying in their own homes and adding features such as elevators to make living more accessible, or moving to customized homes that already include such advantages. According to a Florida State University study, a home elevator can add 10% to the selling price of a home.

Vibrating Micro Motors

SANYO DC Micro Motor Division, Bensenville, IL, has developed the BSY-3089 vibrating micro motor suitable for applications requiring a small footprint on surface-mount circuit boards. The motor measures 11 mm in length, with a 4.4-mm-wide body × 3.4 mm height off the mounting surface. Typical speed is 14,000 rpm with a counterweight of 1.7-mm radius and 2.8-mm length. Mechanical noise is 45 dB max. Electrical noise is controlled by a ring varistor. Standard operating voltage is 2.7 VDC. Load current is approximately 65 mA. Operating temperature range for the vibrating micro motor is -20°C to 70°C, while storage temperature range is -30°C to 85°C.

Digital Signal Controllers

Microchip Technology, Chandler, AZ, has announced the dsPIC33FJ12MC family of motor control digital signal controllers. Hardware features include a motor control PWM with two independent clock sources for motor control algorithms — such as field-oriented control — and active power factor correction using a DSC and an analog-to-digital converter (ADC). The on-chip ADC and motor control PWM are also suitable for power conversion and LED lighting applications.
