BLASI – Motor GR-42X40/64:1/ 24V
The BLASI Motor GR-42X40/64:1/24V powers compact automatic door operators and actuators with its Dunkermotoren GR42x40 DC motor base, extreme 64:1 planetary gear reduction, and 24VDC operation. This high-torque miniature drive unit delivers maximum starting force for small swing doors, low-profile sliding panels, and precision positioning applications in space-constrained installations. Optimized for reliable low-speed, high-power performance, it ensures smooth operation and full compatibility with BLASI control systems.
Product Details
Engineered for BLASI applications requiring maximum torque in minimum space, the GR-42X40/64:1/24V combines the proven Dunkermotoren GR42x40 brushed DC BLASI – Motor—known for its 3100 RPM no-load speed and robust 5.7 Ncm continuous torque—with extreme 64:1 planetary gearing that multiplies output torque to approximately 365 Ncm for effortlessly handling small but heavy entrance panels, ventilation louvers, and barrier actuators.
The ultra-high gear ratio optimizes the compact 42mm diameter BLASI – Motor for slowest-speed, highest-power applications where smooth, controlled motion proves essential for safety-compliant door synchronization and precise positioning. 24VDC operation supports direct integration with standard BLASI power electronics while sealed construction and pre-aligned output shaft eliminate field adjustments common with separately assembled drives.
Technicians value the drop-in ready miniature package with standardized mounting that fits tight architectural envelopes, while facilities managers specify this high-reduction configuration for premium compact entrances, secure vestibules, and specialty applications demanding guaranteed low-speed reliability, overload protection, and silent operation across continuous duty cycles.
